Venue:

J-110, North Campus

Lecturer  Profile

Steven Gao started his  career since 1994 while at China Research Institute of Radiowave Propagation  (China). Then he worked as a Post-doctoral Research Fellow at National  University of Singapore (Singapore), a Research Fellow at Birmingham University  (UK), a Visiting Research Scientist at Swiss Federal Institute of Technology  (ETHZ, Switzerland), a Visiting Fellow at Chiba University (Japan), a Visiting  Scientist at University of California at Santa Barbara (US), and a Senior  Lecturer, Reader and Head of Antenna and Microwave Group at Northumbria  University (UK). Prior to joining Kent as a Professor in Jan. 2013, he was the  Head of Satellite Antennas and RF System Group at Surrey Space Centre,  University of Surrey (UK). He also held short-term visiting appointments at  some institutes including as a Visiting Professor at Northwestern Polytechnic  University (China) and the University of Calabria (Italy).
 He is an Associate  Editor of IEEE Transactions on Antennas and Propagation, a Distinguished  Lecturer of IEEE Antennas and Propagation Society, General Chair of 2013  Loughborough Antennas and Propagation Conference (LAPC), Chair of Special  Session on “Satellite Communication Antennas”  in 2012 IEEE/IET International Symposium on Communication Systems and Networks,  Chair of Workshop on "New Technology Development for Space" in 2015  IEEE Microwave Symposium, etc. He was also a Guest Editor of IEEE Trans on Antennas  and Propagation for Special Issue on "Antennas for Satellite  Communication"(2015), and is Associate Editor of Radio Science (US), a  member of the editorial boards of International Journal of Space Science and  Engineering (US), IET Circuits, Devices and Systems (UK), Chinese Journal of  Electronics (China), Chinese Journal of Radio Science (China), and  Editor-in-Chief for Wiley Book Series on "Microwave and Wireless  Technologies". He is a Plenary Speaker at AES'2014, an Invited Speaker at  IEEE IMS'2015 (USA), IWAT'2014 (Sydney, 2014), SOMIRES'2013 (Japan, 2013),  APCAP'2014 (China, 2014), etc. He is a Fellow of Institute of Engineering and  Technology (IET), UK.
 He has two books  including Space Antenna Handbook (Wiley, 2012) and Circularly Polarized Antennas  (Wiley-IEEE, 2014), over 250 papers and several patents. He received URSI Young  Scientist Award from International Union of Radio Science (URSI), 2002, Japan  Society of Promotion Science (JSPS) Fellowship Award, Japan, 2005, Best Paper  Award, LAPC, 2012, JSPS Award, Japan, 2013, Royal Academy of Engineering  Visiting Fellow Award, UK, 2013, etc.
 Currently he is  Principal Investigator for several research projects, including  "Millimeter-wave intelligent array antennas for next-generation mobile  satellite communications" (FLEXWIN, funded by European Union FP7), “Advanced  reflectarray antennas for space-borne synthetic aperture radars”  (funded by the Royal Academy of Engineering, UK), “Gallium  Nitride integrated millimeter-wave active phased array multi-beam transceivers  for SATellites" (GaNSat, funded by European Union FP7 Space Programme),  "Digital Beamforming Synthetic Aperture Radars onboard micro-satellites  constellations "(DIFFERENT, funded by EU FP7 Space Programme),  "Adaptive multi-band miniaturized antennas for next-generation smart  phones" (funded by industry), etc.

His main areas of  expertise are in antennas, smart antennas, phased arrays, MIMO, satellite  antenna, RF/microwave/millimetre-wave/THz circuits and RF front ends  (high-efficiency RF/microwave power amplifiers, filters), satellite  communications, wireless power transfer, UWB radars, GNSS reflectometry,  synthetic-aperture radars, remote sensing, electromagnetic modelling and small  satellites.

Lecture  Abstract

Smart  antenna is the key technology for broadband satellite communications,  terrestrial mobile communications (4G and 5G) and radar systems, as it can  achieve electronically beam steering towards desired directions while forming  nulls towards interferences. This talk will review the recent development of  smart antennas for satellite communications, and also discuss some case studies  including Ka-band smart antennas for satellite communications on the move,  low-cost smart antennas for Ku-band satellite communications, etc. Discussions  of future trends will be given in the end.
