Abstract:

Since the discovery of efficient leaky-wave radiation from a slot in a wave guide by Oliner, leakywave antennas have attracted a lot of interest in applications that require beam scanning. Printed planar configurations of LWAs have become very popular, due to low cost. After briefly reviewing crucial historical milestones in LWAs, this presentation will focus on recent developments in LWA antenna research and practical outcomes, including some that have the potential to further extend applications of LWAs from current niche scanning applications to mass communications such as wireless local area networks and emerging 5G mobile systems.

Biography:

Professor Karu Esselle received the B.Sc. degree in electronic and telecommunication engineering (first-class honors) from the University of Moratuwa, Sri Lanka, and the M.Sc. and Ph.D. degrees in electrical engineering from the University of Ottawa, Canada. He is a professor of electronic engineering at Macquarie University, Sydney, and the past-associate dean of Higher Degree Research of the Division of Information and Communication Sciences.. He is the chair of the board of management of the Australian Antenna Measurement Facility, deputy director (engineering) of the WiMed Research Center, and elected 2016 chair of both the IEEE New South Wales (NSW) Section and the IEEE NSW Antennas Propagation/Microwave Theory and Techniques Chapter. He directs the Center for Collaboration in Electromagnetic and Antenna Engineering.
