Title: “Satellite Communications Antenna Systems”
Abstract:Antennas are “Eyes and Ears” of satellite communications payloads. 21st century has seen several new satellite services such as local-channel broadcast for direct broadcast satellite service (DBS), high capacity K/Ka-band personal communication satellite (PCS) service, hosted payloads, mobile satellite services using very large deployable reflectors, high power hybrid satellites etc. All these satellite services are driven by the operators need to reduce the cost of satellite and pack more capability into the satellite. Antenna sub-system design, mechanical packaging on the spacecraft, and RF performance become very critical for these satellites. System requirements that drive the antenna designs will be presented initially with brief introduction to satellite communications.
Practical designs for satellite communications using contoured beams, multiple spot beams, and reconfigurable beams will be presented. Multiple beam antenna (MBA) concepts and their advantages compared to conventional contoured beams will be introduced. Various designs of the MBA for DBS, PCS, and MSS services will be discussed along with examples. Advances in multi-band antennas covering multiple bands will be presented. Brief introduction to antenna test and qualification for space applications will be given. Future trends in the satellite antennas will be discussed. At the end of this talk, engineers will be exposed to typical requirements, designs, hardware, software, and test methods used for satellite antenna systems.

Dr. Sudhakar Rao is working as a Technical Fellow at Northrop Grumman Aerospace Systems, Redondo Beach, CA, USA since 2010 where is working on advanced satellites, aircrafts and ground antennas for various military and civilian applications. He received Ph. D in electrical engineeringfrom Indian Institute of Technology Madras in 1980.Dr. Rao worked as a post-doctoral fellow at the University of Trondheim, Norway and then as a research associate at University of Manitoba, Canada during 1981-1983. Over the past 36 years starting from 1983, he worked at Spar Aerospace Limited (now MDA), Boeing Satellite Systems, Lockheed Martin and now at Northrop Grumman and contributed to antenna & payloads for more than 80 different satellites. His work on development of radiation templates for complex radiation patterns of satellite antennas for interference analysis was adopted and recommended by the International Telecommunication Union (ITU)/CCIR in 1992 as the world-wide standard for satellite manufacturers and operators. He authored over 200 technical papers and was awarded with 48 U.S patents and three trade secrets. He authored and co-edited three text book volumes on “Handbook of Reflector Antennas and Feed Systems” that were published in June 2013 by the Artech House.
Dr. Rao is an IEEE Life Fellow and a Fellow of IETE. He received several awards and recognitions that include IEEE Benjamin Franklin Key Award in 2006, Special Invention Award from Boeing in 2002 for a series of patents related to reconfigurable satellites, Delaware Valley Engineer of the Year in 2008, Asian American Engineer of the year award in 2008, IEEE Judith Resnik Technical Field Award in 2009 for pioneering work in aerospace engineering, IETE’s S.N. Mitra award in 2016, NIT Warangal’s Distinguished Alumni of the year award in 2016, IEEE Region 6 Outstanding Engineer Award for 2017 and the 2017 Northrop Grumman’s President Award for innovations. Dr. Rao servedas the Distinguished Lecturer for the IEEE APS during 2015-2017and delivered lectures, keynote talks and invited talks all over the world. He served as the AdCom member for IEEE APS during 2011-2013. He was the Chair for the IEEE APS “Industry Initiatives Committee” during 2011-2015, IEEE APS Fellow Evaluation Committee member during 2015-2017, Associate Editor for the IEEE Antennas & Propagation Magazine’s “Antenna Applications Corner”, Associate Editor for the IEEE Transactions on Antennas & Propagation, and Associate Editor of IEEE AWPL.He is the Executive Committee Member and IEEE APS Liaison for the InCAP series of conferences that started as annual events in India from 2018and is currently being held in Ahmedabadduring Dec 19-22, 2019. Dr. Rao is the guest editor for the special issue on “Satellite Antennas: Recent Advances” published in October 2019 issue of IEEE AP Magazine.
