Short Bio: 
Lei Ge (Senior Member, IEEE) was born in Jiangsu, China. He received the B.S. degree in electronic engineering from Nanjing University of Science and Technology, Nanjing, China, in 2009 and the Ph.D. degree in electronic engineering from City University of Hong Kong, Hong Kong, in 2015.
From September 2010 to July 2011, he was a Research Assistant with the City University of Hong Kong. From April 2015 to October 2015, he was a Postdoctoral Research Fellow at the State Key Laboratory of Millimeter Waves, City University of Hong Kong. He is currently an Associate Professor of College of Electronics and Information Engineering at Shenzhen University, China. His recent research interest focuses on reconfigurable antennas and circuits, MIMO antennas, base station antennas, millimeter-wave antennas, and multiband antennas.
Dr. Ge received the Honorable Mention at the Student Contest of the 2012 IEEE APS-URSI Conference and Exhibition held in Chicago, USA, and the 1st Prize in the Student Innovation Competition of the 2014 IEEE International Workshop on Electromagnetics (IEEE iWEM) held in Sapporo, Japan, in 2014. He was a recipient of the IEEE Antennas and Propagation Society Outstanding Reviewer Award from 2017 to 2018. He was a TPC co-chair, a TPC Member, a Workshop/Tutorial chair and a Session Chair of some international conferences. He has authored more than 80 publications on international journals and conferences including 30 IEEE Transaction papers.

Title: Multi-Band Radiation-Differentiated Antenna

With the continuous development of wireless techniques, various wireless techniques will coexist in a long term to meet the requirements of various application scenes. Antennas, serving as the front-end components of wireless systems, are demanded to meet not only impedance but also radiation requirements of different wireless services in different application scenes. Thus, bands-spanned radiation-differentiated antenna (BSRDA), with the ability of offering different radiation properties (polarization direction/radiation pattern) at different frequency bands, are urgently desired for various wireless services. In this talk, two types of BSRDAs are presented. By properly exciting the operating modes of the patch antennas, these designs can exhibit different polarization and radiation properties over two bands. In addition, the design ideas, results and advantages are also discussed.
