讲座人 Professor Y. Jay Guo
讲座人介绍 Professor Y. Jay Guo is a Fellow of the Australian Academy of Technological Sciences and Engineering (ATSE), a Fellow of IEEE and IET. He earned his Bachelor and Master degrees from Xidian University. Currently, he serves as the Director of Global Big Data Technologies Centre (GBDTC) and Distinguished Professor at the University of Technology Sydney (UTS). Prior this this appointment, he served as Director of a number of research portfolios in CSIRO, Australia. Before joining CSIRO, Prof Guo worked as a R&D leader in the European mobile communications industry for eight years. His research interest includes reconfigurable antennas, wideband and conformal antenna arrays, base-station antennas and advanced wireless communications and sensing systems.
讲座内容 Compared with antenna arrays and reflector and lens antennas, leaky wave antennas have the advantages of simple feeding structure, low profile and inherent scanning ability. In spite of these, leaky wave antennas have remain primarily as an academic pursuit for many years. This is now changing, mostly driven by the needs of low profile and low cost wireless sensing and communications systems. In this talk, we shall review some of the fundamentals of leaky wave antennas and present the recent advances and emerging topics in this field. We shall discuss how to create leaky wave antennas that can scan over a large angular range and be polarization reconfigurable. Most importantly, we shall report a new class of reconfigurable leaky wave antennas that can provide fixed frequency scanning as opposed to the traditional frequency based scanning. It is believed that fixed frequency scanning leaky wave antennas will find wide applications in both wireless and satellite communications systems on moving platforms.
