APACE 2021 - IEEE Asia-Pacific Conference on Applied Electromagnetics

W ELC O ME MESSAGE

Selamat Datang ke APACE 2021!

As the conference general chair, I wish to extend a warm welcome to all participants of APACE2021, which
is the nine-th meeting of the IEEE Asia-Pacific Conference on Applied Electromagetics Conference series.
The series was initiated by IEEE Antennas and Propagation/ Microwave Theory and
Techniques/ Electromagnetic Compatibility chapter of Malaysia in 2005 as part of the chapter’s continuing
efforts to promote research and development in the areas of radio frequency technology and applied
electromagnetics among researchers and industrialists in Malaysia.

2021 also marks the first time the conference comes to Penang and the most triggered moment is for the first
time ever it is conducted virtually due to prolong COVID-19 pandemic issues. Despite the challenge to come
out with significant research outputs worth for publication finding when many of us struggling working
from home, plus economic downturn seen in most countries in the region, APACE 2021 still managed to
attract a good number of papers. This year almost 75 papers were received, and out of these, only about 70 %
were accepted. The reviewing panel completed about 312 reviews, with each paper being allocated a
minimum of three reviewers. This rather stringent evaluation process is necessary to maintain the quality of
papers IEEE conferences are famous for. These papers will be presented over two parallel tracks over two days
at the conference.

As with previous editions of APACE, this year’s meeting also features several distinguished speakers. This
time we are honoured to have three eminent Speaker, IEEE Fellow Professor Cyhthia Furse of Unversity of
UTAH, USA; Professor Akimasa Hirata of Nagoya Institute of Technology, Japan; and Dr Jon Martens of
Anritsu, USA.

Two tutorial speakers, which are Dr Nasimuddin of Institute for Infocomm Research, Singapore; and
Professor Rakhesh Singh Kshetrimayum of Indian Institute of Technology Guwahati, India. We also bring
14 plenary speakers Associate Professor Wayne Rowe, Professor Dr. Ir. Fitri Yuli Zulkifli, Professor Dr Jafri
Din, Professor Zahriladha Zakaria, Professor Ir. Dr. Badrul Hisham Ahmad, Associate Professor Dr. Aloysius
Adya Pramudita, Professor Mohammad faiz Liew Abdullah, Professor Ir. Dr. Mohd Faizal Jamlos, Professor
Alyani Ismail, Professor Haruichi Kanaya, Professor Lim Eng Hock, Professor Ir. Ts. Dr. Kaharuddin
Dimyati, Professor Mohamed Himdi and Professor Omar Ramahi.

Again, the support we received from the industry was encouraging. In particular,
I wish to acknowledge our sincere thanks to our loyal sponsors RF Station and
Comrel Technologies. Many thanks go to the researchers, for their willingness to
share their findings with us and for their support in this event. This meeting
would not have been possible without the support of members of the Organizing
Committee, for which I am eternally grateful.

I wish you a happy virtual conference and hope to see you again in future editions
of APACE, perhaps in physical meeting.

History and Future of Implantable Antennas

Professor Cyhthia Furse
Professor of Electrical and Computer Engineering

University of Utah, Salt Lake City, Utah, USA
____________________________________________

Abst r act
Implantable antennas have been used for communication with medical implants for decades. Since
then, wireless medical telemetry systems and their associated implantable antennas have expanded
rapidly. Implantable medical devices now touch virtually every major function in the human body.
Cardiac pacemakersand defibrillators, neural recordingand stimulation devices, cochlear and retinal
implants are just a few of the many implantable medical devices available today. Wireless telemetry
for these devices is necessary to monitor battery level and device health, upload reprogramming for
device function, and download data for patient monitoring. Emerging medical telemetry devices
have led to recent advances in the design of small, biocompatible antennas that can be implanted in
the human body. This session will track the types of antennas seen in the past, the technologies that
enabled these changes, and prospects for future implantable antennas for medical applications

_________________________________________________

Abst r act
Current microwave and high frequency instrumentation perform many tasks behind the scenes,
even more so in the mm-wave and high modulation rate regimes that are critical for new
communications, imaging, and related application, and it is easy to lose track of how the equipment,
the processing algorithms, the setup/ environment and the signals are interacting. By exploring the
measurement mechanics within some common instruments under practical conditions, it may be
easier to understand where sensitivities or anomalies might increase, how to mitigate them and how
the hardware has been evolving. Through a study of example architectures and measurements,
including those in the 100+ GHz range and those with wide modulation bandwidths where
linearity, dynamic range and other physical metrics are stressed even more, mechanisms and ideas for
better measurements will be explored.

Biogr ap h y
Dr. Jon Martens has been with Anritsu since 1995 where he is currently an Engineering Fellow. His
research interests include measurement system architectures and pathologies, millimeter-wave
circuit and system design, and a wide range of microwave measurement processes to include

_________________________________________________

Abst r act
The human body whose electrical behavior depend on the frequency should be considered in the
modern design of wireless devices which are used in proximity of the human body. Also, safety
assessment of induced electric field or power deposition in the human body is needed to satisfy the
limits prescribed in international standard and guidelines. However, an accurate electromagnetic
modelling with human body is complicated, as it depends not only on the frequency but also the
individual variabilities, environmental factors, actual design of the device and use scenarios. In this
talk, recent progress in modelling of human in electromagnetics is presented. Then, the effect of the
human presence on the wireless devices including wireless communication terminals and wireless
power transfer systems is explained considering typical scenarios. Exposure assessment is also
presented for 5G wireless communications system.

Optimization of Defected Ground Structure (DGS) Using Genetic
Algorithm for Gain Enhancement of Microstrip Antenna

Prof. Dr. Ir. Fitri Yuli Zulkifli
Professor

Universitas Indonesia, Indonesia
__________________________________________________

Abst r act
Defected ground structure (DGS) is a technique for increasing antenna gain by changing the shape of the
ground, without the need to increase the dimensions of the antenna. However, the application of the DGS
technique is generally carried out using an inductive approach which requires high computational resources
and time consuming for the design process. Therefore, to speed up the DGSdesign process, machine learning
methods, especiallygenetic algorithms, isused. Thisstudyproposesa patch antenna DGSoptimization model
to increase the patch antenna gain using genetic algorithm so that the DGS design time can be shortened and
the design process efficiency can be increased. Based on the simulation results, the DGS design without
genetic algorithm is able to increase the bandwidth and gain of the patch antenna by 8.91% and 3.92%,
respectively. Meanwhile, the DGS design optimized by genetic algorithm is able to increase the bandwidth
and gain of the patch antenna by 84% and 50.86%, respectively. In addition, shorter optimization time is
achieved by using genetic algorithm.

Stratiform and Convective Drop Size Distribut ions on Specific
Rain Attenuation in Peninsular Malaysia for Propagation
Ap p licat ion s

Prof. Dr. Jafri bin Din
Director of Wireless Communication Center
Universiti Teknologi Malaysia (UTM), Malaysia
________________________________________________

Abst r act
This work investigates the effects of stratiform and convective raindrop size distributions (DSDs)
on radio waves propagating through the atmosphere and their diurnal variation. The specific
attenuation due to precipitation is derived for frequencies at Ka and Q bands based on three years
of disdrometer data collected in Kuala Lumpur, Malaysia. Separate analyses are carried out for
stratiform and convective events, classified according to their peak rain rate value and grouped into
three different periods of the day, namely morning, evening and night. DSD and rain rate data are
employed to directly derive specific attenuation values by means of the point matching method, as
well as to determine the local power law coefficients of the rain rate to specific attenuation
relationship. The obtained results suggest that radio communication engineers should carefully
consider the effects of the diurnal variation of the DSD, especially for 5G terrestrial applications as
well as Satellite link operating at Ka band and above at the location of interest.

________________________________________________

Abst r act
This paper presents a review of the design and development of matched band-stop filters using
lumped element. It is a compilation of band-stop filter design using lumped-element in order to
investigate the effectiveness of lumped-element. A lumped-element device is a passive device that is
much smaller in size compared to the operatingwavelength in any dimension, resultingin minimum
phase shift between the input and output connections. Based on the reviews, it can be concluded
that lumped-element have the advantage such as smaller in size since no physically long transmission
line. Therefore, accurate mutual inductance between two resonators is not required.

________________________________________________

Abst r act
Small displacement detection has found many applications in numerous field such as, in structure
health monitoring, medical, human to machine interface and disaster management. Small
displacement in a large structure, chest or abdominal wall in human vital sign, motion hand gesture
and in slope location, were became important data that need to obtain for many purposes. Radar
technology is potentially implement for detecting the small displacement in many areas that
previously mention with a feature of non-contact operation and multiple points detection.
However, improvement of some techniques in radar system is needed to overcome resolution
problem in detecting the small displacement. In this paper, the implementation of Frequency

__________________________________________________

Abst r act
Recent years there is an increased demand for high-speed train (HSR) services. Consequently,
onboard high-speed internet access needs to increase as passengers travel to and from work, therefore
introducing new challenges and demand in delivering a seamless internet connection on-board fast-
moving trains. Free Space Optical (FSO) Communications technology promises a bright future for
various applications, due to its cost-effectiveness, ease of deployment, and huge unregulated
bandwidth, which gives it an edge over contemporary technologies. However, due to lack of
significant research on FSO links for railway communications, this paper looks into the single
curved tracks mathematical models for FSO Ground-to-train (G2T-FSO) links proposed to
overcome this issue and satisfy increased demand. Performance evaluation has been conducted in
terms of geometrical properties were assessed in terms of divergence angle, geometrical loss, and
theoretical received power using MATLAB®. The simulation results show significant effects of
geometrical loss when the track curve length is more than 2m towards link performances.

_________________________________________

Abst r act
A new high directivity all-metal helix antenna design for UWB THz radio communication is
presented in this paper. The structure is based on three-dimensional high aspect ratio helix antenna
in order to achieve high directivity. The design is at early stage using full 3D EM simulator to analyze
the performance of the suggested antenna structure. A fractional bandwidth of 68.10% covering
0.52-1.057 THz band was achieved for the structure. Simulation results show that at 0.95 THz, the
maximum directivity and radiation efficiency are 13.4 dBi and 0.9455 respectively. Simulation
results display improvements in directivity (1.3 dBi increase) and bandwidth (2.7% increase) in
comparison with other related works. This high directivity antenna design is a good candidate for
UWB THz radio communication.

A hybrid dipole-loop antenna, which is constructed by connecting a dipole with a loop, is proposed
for designing a compact metal-mountable RFID tag. Here, a pair of dipole arms are closely
integrated with a rectangular loop for achieving a compact size of 60 mm × 30 mm × 2 mm. Also, a
rectangular patch is tactfully placed at the center of the loop for tuning down the tag resonant
frequency to the desired UHF passband. Conjugate impedance match is achievable between the
antenna and the chip by tuning the dimensions of the dipole arm and the rectangular patch. The

Fog radio access network (F-RAN) is an emergent technology that provides a cloud-like services to
the end nodes (ENs) at the edge of the network. Reducing the transmission delay is of a great
importance to boost the performance of FRAN, which can be achieved by optimizing the
probability of FNs. In this context, this paper proposes a framework to obtain the optimum the
probabilityof FNsthat minimizesthe transmission delayin a finite F-RAN. The proposed approach
shows that the optimum probability of FNs is the real root of a polynomial equation of a degree
determined by the path loss exponent (PLE). The results show that optimizing the probability of
FNs can significantly reduce the transmission delay. Moreover it shows that the optimum
probability of FNs decreases with the PLE and number of deployed nodes.

Abst r act
Energy harvesting, also known as energy scavenging, is a method that converts surrounding ambient
energy into useful DC power for low power devices. RF energy harvesting system is demanding
research area of interest in recent times. A RF energy harvester consists of a receiving antenna,
matching, and rectifying circuits. Receiving antenna works to receive RF waves/ energy from the
surrounding and a rectifying circuit converts the EM waves into a DC power. The RF energy
harvesting antennas are instigated in the receiver side to receive the EM waves from the various
ambient RF sources, which are broadly available such as digital TV broadcasting (500-MHz band),
mobile phone services (UHF-band down link), and several other wireless systems. Research on RF
energy harvesting is going on in several areas such as low power wireless sensors, RFID (radio
frequency identification) tags, IoTs, and biotelemetry. With the advances and popularity of wireless
communication devices, large amount of abundant RF energy from surrounding sources are
scattered in our environment. Using an appropriate antenna, these EM waves can be converted into
electrical energy. Linearly polarized antenna receives only noise signals when the receiving antenna
is not aligned with the transmitting antenna. The ambient EM waves exist in all sorts of orientation
and polarization, thushigh performance circularlypolarized antennasor dual-polarized antennasare
preferred for RF energy harvesting applications. A circularly polarized antenna is insensitive to the
multi-path effects and is able to harness RF energy regardless of the device’s orientation. For energy
harvesting systems, a circularly polarized antenna connected to rectifier circuit is expected to convert
RF to dc power independent of source polarization. Different type of antenna and rectenna
structures will be discussed in details for RF energy harvesting applications. An overview of the
antennas for RF energy harvesting will be covered and the specifications for these antennas such as
low profile, wideband, high gain, widebeam, lightweight, compact size, polarization, multiband,
planar/ conformal structure, etc.

Inter-antenna interaction and its effects in MIMO wireless

Dr Rakhesh Singh Kshtherimayum
Professor

Indian Institure of Technology Guwahati, India
__________________________________________

Abst r act
It is a well-established fact that Multiple-input-multiple-output (MIMO) wireless is already
employed in 5G wireless and it is a technology expected to be used in beyond 5G and 6G wireless.
The main advantages of the MIMO wireless in comparison to the conventional Single-input single-
output (SISO) wireless are its two major gains viz. diversity gain (DG) and multiplexing gain (MG).
The MG can be derived from the channel capacity of the MIMO system. But due to utilization of
multiple antennas at the transmitter and receiver, the problem of interantenna.

Interaction (IAI) is inevitable in the MIMO wireless. The two most important IAI
parameters for MIMO antennas are envelope correlation coefficient (ECC) and antenna correlation
coefficient (ACC). The ECC can be accurately calculated from the 3-D radiation patterns of the
MIMO antenna. From the ECC, ACC can be obtained. Once ACC matrix of the MIMO antenna
is available, it can be used to observe the effect of MIMO antenna on the MIMO system’s
performance such as the DG and the MG. It can be also utilized for the calculating the channel
capacity loss (CCL). The CCL for single-user MIMO (SU-MIMO) and multi-user MIMO (MU-
MIMO) will be calculated and investigated for some typical point-to-point MIMO and distributed
MIMO systems respectively. It has been apparent that the ECC for MIMO antenna is the most
important IAI parameter which decide the performance of the MIMO antenna in the MIMO
systems. So the aim and objective of MIMO antenna engineers should be minimizing the ECC. In
wireless domain, IAI has been completely eradicated by techniques such as Spatial modulation. A
brief discussion on such techniques will be initiated. Several MIMO antenna examples will be
provided which minimize mutual coupling and the ECC to a great extent and study their effect on
the MG and the DG will be carried out.

A brief discussion on the evolution of the MIMO systems, from SU-MIMO to MU-MIMO,
MU-MIMO to massive MIMO (mMIMO), mMIMO to cell-free massive MIMO (CF-mMIMO)
will be pursued in this talk.

A1: Antenna and Radiating Elements 1

15:50 Design of an Inset Feed Rectangular Micr ostr ip Patch Antenna
Juhi Jahani, Fathima Joofa, Fathima Zeena and Rajendran Hirshan (South Eastern University of Sri
Lanka, Sri Lanka); W. G. C. W. Kumara (South Eastern University of Sri Lanka & South Asian
Institute of Technology and Medicine, Sri Lanka)

Many types of conventional antennas exist for RF energy harvesting purposes. This energy can be
used for sensor applications. The microstrip patch antenna is a more efficient and better radiation
antenna that can be chosen out of all antennas since it is smaller in size and operates at microwave
frequencies. This work presents the parameter design, simulation, and output testing of a microstrip
patch antenna that can harvest energy from the Wi-Fi with the resonance frequency of 2.4 GHz.
This antenna is a good radio frequency harvester that can absorb the energy spectrum in the band of
interest for Wi-Fi and Wi-Max. Thesimulation of themicrostrip patch antenna wasperformed using
Computer Simulation Technology (CST) and the results obtained are discussed. The return loss of
the antenna will also be discussed using the simulation result. In the fabrication of the antenna, the
patch shape of the antenna was laser printed first using a photo sheet and then was printed on the
copper board. Finally, by using thinner, the shape of the patch was obtained. The specialty of the
microstrip patch antenna is the antenna design itself has the impedance matching feature where we
make the 1 mm gap between the inset feed and the patch. Further, an SMA connector was used at
the feeding point of the antenna since it can feed 50 Ω characteristic impedance. The minimum
voltage expected from the antenna is 0.3 V ac. Finally, the antenna output voltage was tested at
various places. The voltage differs according to the Wi-Fi strength of the place. The output voltage
increases when the Wi-Fi strength is relatively higher.

The meander line antennas (MLAs) are used for small-sized antennas in the self-resonant condition
that capacitive reactance (XD) and inductive (XC) reactance are equal. In the previous study, XD
and XC are not explicitly shown in the structural equation of self-resonance. In this paper, XC, and
XD are derived from the self-inductance of the crank part and the stored charge at the edge area of
the MLA. By equalizing XD and XC, the self-resonant equation is obtained. The self-resonant
structures by the equation and results of electromagnetic simulations agree very well. The usefulness
of the equation is ensured.

A compact circularly polarized antenna for the Global Navigation Satellite System L1 band at 1575
MHz is presented. A circular patch antenna is first designed to operate before being integrated with
four ring slots to achieve circular polarization. The antenna features a bandwidth of 1.96 %in L1,
with an axial ratio bandwidth of 0.896 %. The antenna radiates towards 0 deg. with a realized gain
of 5.58 dB and an angular beamwidth of 96.6 deg.

Technology, Universiti Teknologi Malaysia, Malaysia); Kamilia Kamardin (Universiti Teknologi
Malaysia, Malaysia)

Multi beam radiation characteristics are being required at 5G mobile base station and broadcasting
satellite system. The spherical reflector antenna was proposed for multi beam application. However,
spherical aberration reduced antenna gain. In this paper, the spherical aberration condition is
analytically clarified by employing the focal region ray tracing method for dual spherical antenna
configuration. MATLAB ray tracing program is developed to obtain ray concentration at the focal
region. The calculated results show that the center sphere of the sub-reflector should be large as
much as possible.

Multibeam radiation patterns are requested at the broadcasting satellite antenna. In this paper,
multibeams radiation characteristics are compared between the conventional parabolic and the
spherical reflector antenna using similar specifications. Reflector diameter of 35.8 wavelength at
12.5GHz is selected. A conical horn is employed for the feed radiator. Multibeam radiation patterns
are obtained by using an Electromagnetic Simulator FEKO. The results show that the gain
degradation at 20 beam width shift becomes around 3.2dB for a parabolic reflector antenna and
0.7dB for a spherical reflector antenna with the F/ D = 0.698 antenna configuration.

curved surfaces. Flexible patch antennas are robust light weight antennas which are withstand
mechanical strain up to a certain extent. The type of substrate, materials utilized, processing
techniques, antenna performance, and the surrounding environment all influence the choice of
flexible patch antennas. As a result, there is a wide range of design developments, new materials and
material properties, and specific applications on the market that have proven to be successful.
However, there is a scarcity of knowledge on the electromagnetic properties of the materials
employed. The main purpose of this review is to find the effect of conductive materials and
substratesin research studiesof flexible patch antennas. The importance of conductive materialsand
the various substrates are reviewed in detail for electrical properties and mechanical performance.
The results also show that, the materials as well as processes to produce flexible patch antennas are
presented and compared. Finally, conductive material for the flexible patch antenna and analysis
that must be done to design proper flexible antennas is discussed and areas for future research are
recommended.

This paper serves two purposes, namely, a mini-review of the previous work done in tunnels, and,
prediction of the future trends in tunnel propagation. For the first part, on mini-review, various
aspects of electromagnetic wave propagation in tunnels is presented. This is written based on an
exhaustive search of publications from various databases that covers the said topic, taking into
account the frequency effects, the geometry of tunnels, modelling and measurement approaches, as
well as lastly paying a special focus to the millimeter wave band since this is generally perceived as the
next big thing in wireless communications. From this mini-review, we conclude the paper with an
outlook of the propagation work in tunnels within the foreseeable future.

Fast and accurate response to computational problems is the need of the industry. Hence this
research study aims at finding the correct wavelet for quick and correct solutions to computational
problems related to electromagnetic (EM) wave equations. Three separate EM wave equation-based
computational problems are addressed using the identified appropriate wavelet technique suitable
for this type of computational analysis. Error analysis has also been discussed in this paper.
