IEEE Santa Clara Valley APS Chapter


    Welcome to the SCV-APS web site. Meetings are now being scheduled for the summer and fall. We welcome suggestions for topics and speakers for future meetings.

Upcoming Events

Next Meeting:

The May 23 meeting will feature Karu Esselle, an Antennas and Propagation Society Distinguished Lecturer from Australia.

The meeting will be at Texas Instruments Building E, 2900 Semiconductor Drive Santa Clara, CA 95051

 Dr. Esselle will present a talk on “Many names, many advantages – Are resonant cavity antennas the killer planar space-saving approach to get 15-25 dBi gain?”

No other antenna concept has more names. At present these antennas are known as Fabry-Perot cavity resonator antennas, Partial Reflector Surface (PRS) based antennas, Electromagnetic Band Gap (EBG) Resonator antennas (ERAs) and Two-Dimensional Leaky-Wave Antennas, and more names are forthcoming. Yet they all have more or less the same configuration consisting of a resonant cavity, formed between a partially reflecting superstructure and a fully reflecting (ground) plane. The resonant cavity is excited by a small feed antenna. Hence, they are referred to as resonant cavity antennas (RCAs) in this presentation. This presentation will take the audience through historical achievements of RCA technology, giving emphasis to breakthroughs in the last 10 years. Special attention is given to methods that led to aforementioned bandwidth enhancement and area reduction, dramatic improvement of gain-bandwidth product and unprecedented gain-bandwidth product per unit area demonstrated by RCAs, both theoretically and experimentally. Several choices of superstructures are discussed. The presentation will conclude with yet unresolved issues, which could be addressed in future research.

Professor Karu Esselle, IEEE ‘M (1992), SM (1996), F (2016), received BSc degree in electronic and telecommunication engineering with First Class Honours from the University of Moratuwa, Sri Lanka, and MASc and PhD degrees in electrical engineering from the University of Ottawa, Canada. He is a Professor of Electronic Engineering, Macquarie University, Sydney, Co-Director of WiMed Research Centre and the Past Associate Dean – Higher Degree Research (HDR) of the Division of Information and Communication Sciences. He has also served as a member of the Dean’s Advisory Council and the Division Executive from 2003 to 2008 and as the Head of the Department several times. He is also the chair of the Board of management of Australian Antenna Measurement Facility, and elected Chair of both IEEE New South Wales (NSW) Section, and IEEE NSW AP/MTT Chapter, in 2016 and 2017. Professor Esselle has provided expert assistance to more than a dozen companies including Intel, Hewlett Packard Laboratory (USA) and Cisco Systems (USA). He is an Associate Editor of IEEE Transactions on Antennas and Propagation and IEEE Access.
