讲座人介绍

Dr. Shuai Zhang received the Ph.D. degree in electromagnetic engineering from KTH-Royal Institute of Technology, Stockholm, Sweden, in 2013. In 2014, he joined Aalborg University, Denmark, where he currently works as Associate Professor (tenured) in antennas. In 2010 and 2011, he was a Visiting Researcher at Lund University, Sweden and at Sony Mobile Communications AB, Sweden, respectively. He was also an external antenna specialist at Bang & Olufsen, Denmark from 2016-2017. He has coauthored over 80 articles in well-reputed international journals and conferences, and hold over 14 (US or WO) patents. His research interests include: mobile terminal mmwave antennas, biological effects, CubeSat antennas, UWB wind turbine blade deflection sensing, MIMO antenna systems, and RFID antennas. He is also a reviewer for all the IEEE and IET journals in antenna areas.

讲座内容

As one of the key technologies in future 5G cellular communication systems, millimeter wave (mmwave) will be applied for 5G mobile handsets. In these systems, beam steerable arrays with high gain have to be utilized at both base stations and user terminals in order to overcome the path loss. At base stations, there is ample room for complex antenna array designs. However, in mobile terminals, there is very limited space left for 5G arrays after accommodating 2G, 3G and 4G antenna systems. The only power supply in a cellphone is a small battery, which requires low-loss and low-cost beamforming. Moreover, user’s mobility and blockage also rise some more new issues. This presentation will focus on introducing the challenges in mm-wave 5G mobile handsets. As some examples, recent progress of the antenna group at Aalborg University will be introduced in the area of mm-wave beam-steerable antenna arrays and their biological effects for 5G mobile terminals. Integration of terminal antennas at mmwave and sub 6 GHz will also be one part of this presentation.
