He developed antenna payloads for more than 65 satellites including first mo- bile satellite M-Sat and first Direct Broadcast Satellite with local channels (DirecTV-4S). His work on development of radiation templates for complex radiation patterns of satel- lite 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. From 1996-2003 he worked as Chief Scientist/Technical Fellow at Hughes/Boeing Satellite Systems and developed multiple beam antennas and reconfigurable beam payloads for commercial and military applications. He authored over 165 technical papers and has 44 U. S. patents. Dr. Rao became Fellow of IEEE in 2006 and a Fellow of IETE in 2009. He received best reviewer recognition by the IEEE Transactions on Antennas and Propagation Journal for the years 2014 and 2015. Dr. Rao is appointed as the Distinguished Lecturer by the IEEE APS for a three year period (2014-2016).

Abstract of the Talk
21st century has so far seen several new satelliteservices such as local-channel broadcast for Di-
rect Broadcast Satellite service (DBS), high capacityK/Ka-band personal communication satellite (PCS)service, hosted payloads, mobile satellite services us-ing very large deployable reflectors, high power hybridsatellites etc. It is important to integrate more capa-bilities into the satellite while reducing the cost. An-tenna sub-system design, mechanical packaging on thespacecraft, and RF performance become very criticalfor these satellites. This talk will cover recent develop-ments in the areas of antenna systems for FSS, BSS,PCS, and MSS satellite communications. It includesadvanced antenna system designs for contoured beams,multiple beams, and reconfigurable beams, MultipleBeam Antenna (MBA) concepts with its advantages,recent advances in feed technology and reflector tech-nology, introduction to remote sensing antennas, ad-vanced high power test methods for satellite payloads,and future trends in satellite antenna systems.
