Biography:Dr. Zhang is currently an associate professor in the Center of Nanoelectronics and School of Microelectronics, Shandong University, China. He received his B.S. and M.S. degrees in Electrical Engineering from the Beijing Institute of Technology, Beijing, China, in 2006 and 2009, respectively, and his Ph.D. degree from the Department of Electrical and Computer Engineering, University of Delaware, DE, US in 2016. From 2016 to 2018, he worked as a post-doctoral researcher at the Shandong University. His research interests include microwave, millimeter-wave, and terahertz antennas, arrays, and circuits, terahertz signal sources and detectors, multilayer high- frequency circuits, reconfigurable and tunable metamaterial and surface plasmon devices, MMIC integration, electro- optics and RF-photonics systems, and their applications. He is the member of the IEEE, and a frequent reviewer of many international journals, e.g., IEEE Trans. Antennas Propag., IEEE Trans. Microw. Theory Tech., and IEEE Microw. Mag.

Speech Title: Millimeter Wave Antennas and Circuits on Multilayer Liquid Crystal Polymer Substrates

Abstract: Millimeter wave (mmW) frequencies have gained great interest in wireless communication with high data transmission rate, compact radar with high sensitivity, and fast imaging with high spatial resolution. Among these applications, many platforms require small size, weight, and power consumption (SWaP) critically, which could be alleviated by using multilayer circuits. In this talk, I will report our recent progresses on flexible multilayer liquid crystal polymer (LCP) based mmW devices at E-band and above, including ultra-wideband (UWB) antennas, circuit transitions, filters, and their applications in electro-optic systems.
