Abstract: This talk is focused on the recent research of microwave and millimeter-wave (MMW) system applications at National Taiwan University (NTU). Several joint research efforts were supported by III-V and silicon-based monolithic microwave/MMW integrated circuits designed in NTU. Our MMICs supported a couple of radio telescope systems, namely, Array for Microwave Background Anisotropy (AMiBA), and Atacama Large Millimeter Array (ALMA) systems. A pair of CMOS based 38-GHz transmit/receive chips, together with GaAs pHEMT LNA and PA, have also been developed to support the 38-GHz 5-G RF front end system with an electronic beam steering capability via a pair of 32-element Tx/Rx phased arrays. The similar 38-GHz transmit/receive chips have been modified for an application on the drone to transmit the 8K/4K video in real time for wild animal monitoring. Another developed microwave system is a harmonic radar for the tracking of bees in order to help entomologists to identify the cause of colony collapse disorder (CCD) of the bees. Brief descriptions of each system and application will be presented, along with the microwave/MMW circuit development at NTU.

Bio: Prof. Huei Wang was born in Tainan, Taiwan, on March 9, 1958. He received the B. S. degree in electrical engineering from National Taiwan University, Taipei, Taiwan, 1980, and the M. S. and Ph. D. degrees in electrical engineering from Michigan State University, East Lansing, Michigan in 1984 and 1987, respectively. Dr. Wang joined Electronic Systems and Technology Division of TRW Inc. in 1987. He has been an MTS and Staff Engineer responsible for MMIC modeling of CAD tools, MMIC testing evaluation and design and became the Senior Section Manager of MMW Sensor Product Section in RF Product Center. He joined the faculty of the Department of Electrical Engineering of National Taiwan University, as a Professor in February 1998.  He served as the Director of Graduate Institute of Communication Engineering from Aug. 2006 to July 2009, and the Associate Dean of College of Electrical Engineering and Computer Science of National Taiwan University from Aug. 2016 to July 2018. He has been Life National Chair Professor of the Taiwan Ministry of Education since 2014, and has been appointed as National Taiwan University Chair Professor since 2016.
