主 题： Low-Cost Smart Antennas Based on the Frequency Selective Surfaces
内容简介： Smart antenna is the key technology for broadband satellite communications, terrestrial mobile communications (4G and 5G), radar and Internet of Things. It can achieve electronically beam steering towards desired directions while forming nulls towards interferences. The traditional smart antennas and phased array systems are, however, very complicated, bulky and expensive, which make them difficult for civilian applications. For commercial applications, it is important to investigate novel smart antennas which can have small size, high efficiency and low cost. This talk will review the state-of-the-art development of low-cost small smart antennas for terrestrial and satellite communications. Some case studies including several low-cost smart antennas based on the frequency selective surfaces (FSS), recently developed at the University of Kent, will be discussed in details. A conclusion and future outlook will be given in the end.
Steven Gao is Chair Professor of RF and Microwave Engineering, and the Director of Post-graduate Research at the University of Kent, UK.
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 (ETH Zurich, 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), and Head of Satellite Antennas and RF System Group at Surrey Space Centre, University of Surrey (UK). He joined Kent as a Professor in Jan. 2013.
Prof. Gao is an Associate Editor of IEEE Transactions on Antennas and Propagation, IEEE Access, Radio Science and IET Circuits, Devices and Systems, and the Editor-in-Chief for Wiley Book Series on "Microwave and Wireless Technologies". He was a Distinguished Lecturer of IEEE Antennas and Propagation Society (2014-2016), General Chair of 2013 Loughborough Antennas and Propagation Conference, Guest Editor of IEEE Trans on Antennas and Propagation for Special Issue on "Antennas for Satellite Communications"(2015), and is a member of the editorial boards of International Journal of Space Science and Engineering, Chinese Journal of Electronics (China), etc. He gave invited talks at many international conferences (e.g., Plenary Speaker at AES'2014, Invited Speaker at iWAT 2017, IEEE APWC 2017, UCMMT 2017, APCAP 2014, etc). He is a Fellow of IET, UK, and a Fellow of Royal Aeronautical Society.
He published 2 books (<<Space Antenna Handbook>>, Wiley, 2012; <<Circularly Polarized Antennas>>, Wiley-IEEE, 2014), >300 papers and several patents. He received the 2016 IET Premium Award for the Best Paper in IET Microwave, Antennas and Propagation. 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, mobile communications, wireless power transfer, UWB radars, passive radars, synthetic-aperture radars, remote sensing, electromagnetic modelling and small satellites.
