Dr. Karmakar obtained PhD in ITEE from the University of Queensland in 1999. Dr. Karmakar''s PhD work on Antennas for Mobile Satellite Communications was elected one of the top ten research findings at UQ in 1998 and 3rd best student paper in 1997 APMC and published in UQ News, Canberra Times, and ABC Radio. An Australian defense analyst hailed this design as the first fully planar low-cost phased array antenna designed in Australia. In 2004 Dr. Karmakar formed RFID and Antenna Research Group at Monash University. The group is supported by 4 ARC funded projects which are worth > $2M.
In 2006 he initiated research on chipless RFID physical layer development at Monash University with supports from an ARC Discovery Grant DP0665523: Chipless RFID for Barcode Replacement. The invention of Chipless RFID generated 2 Australian and 2 international (PCT) patents (pending), 1 scholarly book, 16 scholarly book chapters, 7 refereed journal and 22 conference papers. This is the first chipless RFID tag to combine RFID with the ultra-wideband (UWB) technology. His recent industry interactions have initiated new research collaboration LP0989652: Printable Multi-Bit Radio Frequency Identification for Banknotes. This project was elected one of only ten best research proposals (out of approximately 2,000) by ARC in October 2008. He is a CI of ARC SRI: Bionic Vision (worth $8M) and will provide intellectual leadership in the wireless division of the research team. Dr. Yang Yang obtained his PhD degree in Electrical and Computer Systems Engineering from the Faculty of Engineering, Monash University, Australia in June 2013.
During his Ph.D. work, he developed the analogue and digital prototypes of RF based wireless monitoring system for sleep apnoea patients. Dr. Yang was visiting Chang Geng University in Taiwan from August 2011 to January 2012 and achieved the outstanding research outcomes during the limited visiting period. The proposed project involved various designs of power amplifiers (classified as Class AB, Class E, Class F, Dorothy and distributed PA), oscillators/VCOs (particularly at Class E, Class F and cross-coupled prototypes). The process applied was 350 nm GaN HMENT, and the designed oscillators have reached a considerably high output power of 38.8 dBm (7.
6 Watts) with an efficiency of 75% in simulation. The fabricated designs have realised a wireless power transmission range of 1-3 cm. The concept has been tested on a rectifier prototype successfully powering up a LED. This design will be applied on wireless monitoring devices for sleep apnoea diagnosis. Beside the hardware prototypes, the achievement contains 12 international publications including 2 book chapters, 5 international journals and 5 international conference papers. Dr. Yang Yang joined Macquarie University in Apr 2015 as a Senior Research Associate focusing on research of reconfigurable antennas and the relative applications in biomedical and telecommunication industries. Dr.
Abdur Rahim Dr. Abdur Rahim obtained his PhD degree in Electrical and Computer Systems Engineering from the Faculty of Engineering, Monash University, Australia in July 2014. His PhD thesis work is on cooperative virtual multiple input multiple output (MIMO) network for wireless body area network (WBAN) to enhance the signal quality and detection in wireless sleep apnoea monitoring physiological parameters. In his PhD design project he developed test beds for wireless monitoring two physiological parameterselectrocardiogram (ECG) and electromyography (EMG) signalsfrom a patient. He developed in-house built algorithm for cooperative WBAN virtual MIMO system using energy efficient network coding. He designed and developed space time coding using FPGA for WBAN. He also designed and developed a rectangular patch antenna at 5.8 GHz for monitoring spatial diversity performance for WBAN in sleep patient He developed various signal processing algorithms for cooperative communication in WBAN such as amplify-and-forward, decode-and-forward, estimate-and-forward and distributed space time coding.
He also developed the WBAN channel model suitable for wireless sleep apnoea monitoring. He earned Master of Engineering in Telecommunications from Asian Institute of Technology, Thailand in 2005. In his MSc thesis he developed blind channel estimation in MIMO for multi-carrier code division multiple access (MCCDMA) technique for wireless communications. He served as a faculty member at the Electrical and Electronic Engineering (EEE) department of International Islamic University, Chittagong, Bangladesh from 2000 to 2009. He taught digital signal processing, digital communications, cellular mobile systems, information theory and coding, digital logic design and signals and systems. He obtained his bachelor of engineering (BSc) degree in electrical and electronic engineering from Chittagong University of Engineering and Technology, Bangladesh in 1999. He is currently working as an electronic engineer at Polar Electronic Industries Pty. Ltd.
, Melbourne, Australia. He is responsible to design and develop filters, resonators, power dividers and combiners, matching design of communication antenna. He also is an active member of Monash Microwave Antennas RFID and Sensor Research (MMARS) group. His research area of interests include virtual MIMO, Antenna design, Sleep Apnoea monitoring and network coding.
