Abstract:  

Smart antenna is a key technology for mobile communications, satellite communications, radar and sensors as it can enable the wireless systems to achieve the optimum performance by electronically steering its maximum radiation towards the desired directions while forming nulls against interfering sources. Traditional smart antennas are, however, complicated in structure, bulky, power hungry and costly. For commercial applications, it is important to reduce the size, mass, power consumption and cost of smart antennas. Firstly, this IEEE DL talk will present an introduction to smart antennas, followed by a brief review of various types of low-cost smart antennas. Then, several recent examples of low-cost smart antennas will be presented and discussed. These antennas are capable of achieving electronic beam steering within a wide angular range, while having compact sizes, low power consumption and low cost. A conclusion will be given in the end and discussions.

Bio:

Professor Steven (Shichang) Gao is Chair of RF and Microwave Engineering at School of Engineering and Digital Arts, University of Kent, UK. Prior to joining Kent, he was the Head of Space Antennas and RF System Group at Surrey Space Centre, University of Surrey (UK). He is also a Visiting Professor at Northwestern Polytechnic University (Xi'an, China) and the University of Calabria (Italy). He is an IEEE AP-S Distinguished Lecturer (2014-2016), General Co-Chair of Loughborough Antennas and Propagation International Conference (LAPC), UK, 2013, and Chair of Special Session on “Satellite Communication Antennas” in IEEE/IET International Symposium on Communication Systems and Networks, Poland, 2012, etc. Recently he was appointed as the Editor-in-Chief for Wiley Book Series on "Microwave and Wireless Technologies".  He has two books including Space Antenna Handbook (Wiley, 2012) and Circularly Polarized Antennas (Wiley-IEEE, 2014), over 180 technical papers, 10 book chapters and several patents in smart antennas and RF. 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. His main areas of expertise are in antennas, space antennas, smart antennas, phased arrays, RF/microwave/millimetre-wave circuits and RF front ends (high-efficiency RF/microwave power amplifiers, filters), satellite communications, mobile communications, UWB radars, GPS antennas and reflectometry, synthetic-aperture radars, remote sensing, electromagnetic modelling and small satellites (micro-satellite, mini-satellite, nano-satellite).
