Dr. Ashutosh Kedar of Electronics and Radar Development Establishment (LRDE), DRDO, Bangalore

Active phased array antennas or active electronically scanned antennas (AESA) have been a constant source of attraction for last 4-5 decades. The technology has evolved vigorously with phenomenological research activities being carried out worldwide. AESA may be considered as a system of systems comprising of various systems/sub-systems within itself. Now a days, AESA has even found its applications in commercial arenas like wireless communication due to ever-growing demand of bandwidth, capacity, etc., with the advent of 5G technology. The commercialization of AESAs is made possible due to the evolution of new semiconductor technologies like GaN, SiGe, CMOS, etc. with a great reduction in the cost and the form factor involved. An overall reduction in SWAP-C resources has made the commercialization possible.

This talk is going to discuss an overview of AESA technologies and the various subsystems involved along with the few critical technologies involved in their development. A brief on theoretical/commercial analysis tools will be presented which come handy in the development of the AESAs. The talk will conclude upon futuristic possibilities linked to the current scenario required for upgradation of AESAs.
