嘉宾简介:

Zhongxiang Shen received the B. Eng. degree from theUniversityofElectronic Scienceand Technology of China,Chengdu,China, in 1987, the M. S. degree from Southeast University, Nanjing, China, in 1990, and the PhD degree from the University of Waterloo, Waterloo, Ontario, Canada, in 1997, all in electrical engineering.

From 1990 to 1994, he was with Nanjing University of Aeronautics andAstronautics,China. He was with Com Dev Ltd., Cambridge, Canada, as an Advanced Member of Technical Staff in 1997. He spent six months each in 1998, first with the Gordon McKay Laboratory, Harvard University, Cambridge, MA, and then with the Radiation Laboratory, the University of Michigan, Ann Arbor, MI, as a Postdoctoral Fellow. In Jan. 1999, he joined Nanyang Technological University (NTU), Singapore, as an assistant professor. He is currently a Full Professor in the School of Electrical and Electronic Engineering, NTU. Dr. Shen served as the Chair of the IEEE MTT/AP Singapore Chapter in 2009. He was the Chair of IEEE AP-S Chapter Activities Committee from Jan. 2010 to July 2014. He is currently the Secretary of the IEEE AP-S and an Associate Editor of the IEEE Transactions on Antennas and Propagation.

Dr. Shen is an IEEE Fellow. His research interests include design of small and planar antennas for various wireless communication systems, analysis and design of frequency-selective structures, hybrid numerical techniques for modeling RF/microwave components and antennas. He has authored or co-authored more than 180 journal papers (among them 100 were published in IEEE Journals) and presented more than 160 conference papers.

讲座内容:
In this talk, I will share our recent experience in designing several end-fire antennas of extremely low profile. These end-fire antennas should be mounted on a conformal conducting surface and can operate over a wide frequency band (at least 100% fractional bandwidth). After some basic considerations about end-fire antennas, I shall review existing designs of wide-band and end-fire antennas. After that, three novel wide-band end-fire antennas will be introduced in details: narrow H-plane horn antenna, surface-wave antenna, and log-periodic monopole antenna. In the end, I shall also mention a few end-fire antennas that are worthy investigation in the future.
