In this talk, the development of millimeter-wave (MMW) RFICs in National Taiwan University for the past years will be presented, including both GaAs and Si-based MMW MMICs for transceiver applications. The design of the embedded MMW antennas/array by using multilayer substrates, can be either in low temperature cofired ceramic (LTCC) or low loss printed circuit board (PCB). The short wavelength of MMW makes it possible to realize a MMW transceiver module with antenna array in the size of a typical IC package in size of few centimeters. By embedding the antennas into suitable packaging substrate, for example, LTCC, and using flip-chip interconnect between die and substrate, a package with low loss at MMW frequency range can be realized. The multi-layer structure of LTCC allows the radiation of antenna structure not only in planar direction, but also in vertical direction.
Huei Wang (S’83-M’87-SM’95-F’06) was born in Tainan, Taiwan, on March 9, 1958. He received the B. S. degree in electrical engineering from National Taiwan University, Taipei, Taiwan, Republic of China in 1980, and the M. S. and Ph. D. degrees in electrical engineering from Michigan State University, East Lansing, Michigan in 1984 and 1987, respectively. During his graduate study, he was engaged in the research on theoretical and numerical analysis of electromagnetic radiation and scattering problems. He was also involved in the development of microwave remote detecting/sensing systems. Dr. Wang joined Electronic Systems and Technology Division of TRW Inc. since 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 visited the Institute of Electronics, National Chiao-Tung University, Hsin-Chu, Taiwan, in 1993 to teach MMIC related topics and returned to TRW in 1994. He joined the faculty of the Department of Electrical Engineering of National Taiwan University, Taipei, Taiwan, Republic of China, as a Professor in February 1998. He served as the Director of Graduate Institute of Communication Engineering from Aug. 2006 to July 2009, and he is currently the Associate Dean of College of Electrical Engineering and Computer Science of National Taiwan University. Dr. Wang is a member of the honor society Phi Kappa Phi and Tau Beta Pi. He received the Distinguished Research Award of National Science Council, Taiwan, at 2003. He was the Richard M. Hong Endowed Chair Professor of National Taiwan University in 2005-2007. He was elected as an IEEE Fellow in 2006, and has been appointed as an IEEE Distinguished Microwave Lecturer for the term of 2007-2009. Dr. Wang received the Academic Achievement Award from Ministry of Education, Taiwan, in 2007, and the Distinguished Research Award from Pan Wen-Yuan’s Foundation in 2008. He has been Life National Chair Professor of Ministry of Education, Republic of China since 2014, and has been appointed as National Taiwan University Chair Professor since 2016.
