Yue Ping Zhang is a full Professor of Electronic Engineering with the School of Electrical and Electronic Engineering at Nanyang Technological University, Singapore, a Distinguished Lecturer of the IEEE Antennas and Propagation Society (IEEE AP-S), and a Fellow of IEEE. 

Prof. Zhang was a Member of the Field Award Committee of the IEEE AP-S (2015-2017), an Associate Editor of the IEEE Transactions on Antennas and Propagation (2010-2016), and the Chair of the IEEE Singapore MTT/AP joint Chapter (2012). 

Prof. Zhang has published numerous papers, including two invited papers in the Proceedings of the IEEE and one invited paper in the IEEE Transactions on Antennas and Propagation. He holds 7 US patents. He received the Best Paper Award from the 2nd IEEE/IET International Symposium on Communication Systems, Networks and Digital Signal Processing, July 18–20, 2000, Bournemouth, U.K., the Best Paper Prize from the 3rd IEEE International Workshop on Antenna Technology, March 21–23, 2007, Cambridge, U.K., and the Best Paper Award from the 10th IEEE Global Symposium on Millimeter-Waves, May 24–26, 2017, Hong Kong, China. He received the prestigious IEEE AP-S Sergei A. Schelkunoff Prize Paper Award in 2012.

Prof. Zhang was selected by the Recruitment Program of Global Experts of China as a Qianren Scholar at Shanghai Jiao Tong University (2012). He was awarded a William Mong Visiting Fellowship (2005) and appointed as a Visiting Professor (2014) by the University of Hong Kong. 

Prof. Zhang has made pioneering and significant contributions to the development of the antenna-in-package (AiP) technology that has been widely adopted by chip makers for millimeter-wave applications. His current research interests include the development of antenna-on-chip (AoC) technology and characterization of chip-scale propagation channels at terahertz for wireless chip area network (WCAN).

"Differential Microstrip Patch Antennas"

The earliest antennas implemented by Hertz for the discovery of radio waves were of the dipole and loop varieties, which are differential in nature. It was Marconi who introduced the ground concept into antennas and developed single-ended monopole antennas for wireless transmission. Compared with differential antennas, single-ended antennas are smaller and therefore have dominated in antenna designs. Compared with single-ended circuits, differential circuits permit higher linearity and lower offset and make them immune to power supply variations, temperature changes, and substrate noise. As a result, differential circuits have dominated in integrated circuit designs. Differential circuits call for differential antennas. This is particularly essential in highly integrated system-on-chip and system-in-package solutions, where the system ground plane may be much smaller than one free-space wavelength. Differential antennas perfectly marry (match) with differential circuits. No lossy balanced/unbalanced conversion circuit is needed. As a result, the receiver noise performance and transmitter power efficiency are improved. 

This talk will focus on differential microstrip patch antennas. First, the cavity model is expanded to analyze the input impedance and radiation characteristics of these antennas. Then the design formulas to determine the patch dimensions and the location of the feed point for single-ended microstrip patch antennas are examined to design differential microstrip patch antennas. The condition that links the patch width, the locations of the probe feeds, and the excitation of the fundamental mode is given. Next, two differential microstrip antennas are illustrated with one in low-temperature co-fired ceramics for 60-GHz radios and another in CMOS for 650-GHz imagers. Finally, differential microstrip shorted patch and planar inverted-F antennas are highlighted.
