“A remote healthcare monitoring system using radio over fibre network”
By Prof. Ir. Dr. Kaharudin Dimyati
With the emergence of Wireless Sensor Network (WSN), developing wireless health care monitoring systems employing various body technologies has become a keen area of interest in many countries of the world today. Wireless body sensor devices can reach an advance level of human body monitoring utilizing various transmission and data analytics techniques. Thus, wearable wireless sensor-based system is intended to provide better personal health management, ubiquitous monitoring health condition, better quality treatment and healthcare, along with allowing efficient circuit integrations, reliable vital signal measurements, low operation costs and optimum power usage. Therefore, the work presented in this keynote aims to integrate artificial intelligence in the domain of healthcare monitoring using mobile device and application, and wearable sensor patch with various ingestible sensors, which will be connected each other to make it an Internet of things-5G (IoT-5G) network. The IoT-5G based sensor networks are integrated where all the data will be securely transferred and stored
in hospital management databases. All the data base will be controlled by the system application which works as a platform and connected via optical fiber with all other databases of the patient’s present hospital. The AI based sensors will produce a computerized diagnosis for the different kind of diseases. Along with this application the platform will also have the ability to receive data/give commands to AI attached sensors which eventually helps to detect and predict the cancer’s normal and abnormal cells.

“Compact Metal-mountable UHF RFID Tag Antennas”
By Prof. Ts. Dr. Lim Eng Hock
In recent years, applications of UHF RFID tagging systems (860 MHz-960 MHz) have been growing rapidly in many sectors such as retail, logistics, transportation, and tracking management. Passive UHF tag, which is a transponder composed of a microchip and a microwave antenna, is able to provide long read range at low cost. However, mounting a UHF tag antenna on metal is challenging as its radiation performance can deteriorate significantly. When a tag antenna is placed in the vicinity of a conductive surface, the radiated fields of the image current and the antenna itself cancel out each other, resulting in poor radiation efficiency. In this talk, the design methodologies and tradeoffs of the metal-mountable UHF tag antenna will be discussed. Folding techniques will be introduced for designing various flexible tag antennas using the soft PET (polyethylene terephthalate) substrate. It will be shown that designing a UHF tag antenna usually requires strenuous effort to make tradeoffs between radiation efficiency, impedance bandwidth, and tag size.

“Related antenna measurements & EMC freq. band”
By Dr. Satoru Kurokawa
Recent progresses in wireless communication technologies are remarkable for broadband wireless internet and mobile communication systems. First step of 5th generation mobile network uses around 3.7, 4.5 and 28 GHz frequency bands in Japan. Radiated electromagnetic interference (EMI) measurement must be done in the radiated electromagnetic field intensity using broadband antennas up to 18 GHz. To evaluate the antenna characteristics for these frequency bands, we usually use double-ridged guided-horn antennas up to 18 GHz and WR-28 band standard gain horn antennas from 26.5 to 40 GHz as standard antennas. In this talk, we show our proposed free space far field antenna factor measurement method using time domain and pulse compression techniques for EMI broad band antennas. Further, we explain our proposed single antenna calibration method for EMI broad band antennas. Then, we also show our proposed single cut-plane near-field to far- field transform method for base-station antennas. Finally, we explain our developed bi-directional optical-fiber-link transceiver systems that can replace coaxial cables in many measurements.
Dr. Satoru Kurokawa received B.E. and M.E. degrees in electrical engineering from Chiba University, Chiba, Japan, in 1987 and 1989, respectively, and a Ph.D. degree from the Department of Communication and Computer Engineering, Kyoto University, Kyoto, Japan, in 2003. He has been working as a senior researcher and a group leader of electromagnetic field standard research group, National Metrology Institute of Japan, National Institute of Advanced Industrial Science and Technology, Ibaraki, Japan, since 2003.

“Theory of Characteristic Modes and its Applications”
By Prof. Dr. Hiroyuki Arai
This talk presents the theory of characteristic modes (CM) given by Harrington and Mautz to show its basics and formulation in detail. A series resonance of RLC circuit, eigenmodes of CM, and natural modes are explained to show physical basics of antenna resonance. The CM analysis tools built in commercially available simulation software are also introduced with several examples. The accuracy of CM is verified by using fundamental antenna elements, such as a half wavelength dipole, one wavelength loop and rectangular microstrip antennas in terms of eigen-frequency and unloaded Q factor. In practical simulations, spurious and hybrid modes are often appeared in numerical results, in particular, due to the symmetry of antenna geometry. Mode tracking and current correlation used in the simulation improve the accuracy of CM analysis. This topic is presented by several examples. Typical applications of CM, smart phone antennas utilizing ground plane (chassis) of phone and HF antennas of platform such as aircraft and vehicle, are discussed how to use CM analysis in practical applications.
