IEEE Antennas and Propagation Society Distinguished Lecturer Program



Recently, millimeter wave (mmW) technology has attracted much interest in high speed wireless communications, high resolution imaging systems, and vehicular radar systems. Antenna development at mmW bands has many unique challenging issues from design, fabrication to measurement. The designs usually suffer from high losses and difficult integration into other circuits. The fabrication is often associated with critical requirements in terms of tolerance. The measurement has been position as the toughest aspect in mmW antenna development due to the expensive testing setup, high sensitivity to the connection between antenna under test and feeding system, customized calibration setup and procedure. Using substrate-integration technology, the antennas will be fabricated onto circuit boards such as printed circuit board, low-temperature co-fired ceramic, and semiconductor substrate to reduce cost, size, transmission loss and enhance integration into circuits. This talk will brief the design challenges in mmW antenna design and substrate-integration technology first. After that, recently developed substrate-integrated high gain antenna arrays for 60-270 GHz applications are exemplified with the introduction of the latest built measurement system up to 325 GHz. Last, the comments on the development of substrate-integration technology in antenna design at mmW and submmW bands are provided.




Professor Zhi Ning Chen received his BEng, MEng, and PhD degrees all in Electrical Engineering from the Institute of Communications Engineering (ICE), China and his second PhD degree from University of Tsukuba, Japan, respectively.

During 1988-1995, he worked at ICE as a Lecturer and later an Associate Professor, as well as at Southeast University, China as a Postdoctoral Fellow and later as an Associate Professor. Professor Chen joined the City University of Hong Kong as a Research Assistant and later a Research Fellow in 1995-1997. In 1997, he conducted his research at the University of Tsukuba, Japan supported by the Japan Society for the Promotion of Science (JSPS) Fellowship. In 2001 and 2004, he visited the University of Tsukuba under a JSPS Fellowship Program (senior level). In 2004, he worked at IBM T. J. Watson Research Center, USA as an Academic Visitor. During 1999-2012, he worked with the Institute for Infocomm Research (I2R) (formerly known as Centre for Wireless Communications and Institute for Communications Research) as Member of Technical Staff (MTS), Senior MTS, Principal MTS, Senior Scientist, Lead Scientist, and Principal Scientist as well as Head for RF & Optical Department. In 2012, he joined the Department of Electrical and Computer Engineering, National University of Singapore as a Professor and is concurrently holding a joint appointment in I2R as Advisor as well as Visiting/Adjunct/Guest Professor positions at Southeast University, Nanjing University, Shanghai Jiaotong University, Tsinghua University, Tongji University, University of Science and Technology, China, Dalian Maritime University, Chiba University, and City University of Hong Kong. He visited the “Laboratoire des Signaux et Systèmes”, UMR8506 CNRS-SUPELEC-Univ. Paris Sud, in Gif-sur-Yvette as a senior DIGITEO Guest Scientist in 2013.

Professor Chen has been the founding General Chairs of International Workshop on Antenna Technology (iWAT), International Symposium on InfoComm & Media Technology in Bio-Medical & Healthcare Applications (IS 3T-in-3A), International Microwave Forum (IMWF) as well as Asia-Pacific Conference on Antennas and Propagation (APCAP).

Professor Chen is currently interested in engineering electromagnetics and antennas for microwaves, mmW, submmW, and THz systems. He has published 450 technical papers and authored/edited the books entitled Broadband Planar Antennas, UWB Wireless Communication, Antennas for Portable Devices, and Antennas for Base Stations in Wireless Communications. He also contributed to the books entitled UWB Antennas and Propagation for Communications, Radar, and Imaging, Antenna Engineering Handbook as well as Microstrip and Printed Antennas. He is working on Handbook of Antenna Technologies (Springer Reference) as Chief Editor. He is holding 32 granted/filed patents with 31 licensed deals. He is the recipient of ASEAN Outstanding Engineering Achievement Award 2013, International Symposium on Antennas and Propagation Best Paper Award 2010, the CST University Publication Award 2008, IEEE AP-S Honorable Mention Student Paper Contest 2008, IES Prestigious Engineering Achievement Award 2006 and 2013, I2R Quarterly Best Paper Award 2004, and IEEE iWAT 2005 Best Poster Award.

Professor Chen is a Fellow of the IEEE for the contribution to small and broadband antennas for wireless applications. He is serving IEEE Trans Antennas and Propagation as an Associate Editor and served IEEE Antennas and Propagation Society as a Distinguished Lecturer. (
