Professor Steven Gao, University of Kent, UK; IEEE APS Distinguished Lecturer
He 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, 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).
Smart antenna is a key technology for 5-G 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.
