Gregorian reflector antenna
WebJan 9, 2024 · GSAT-7A military communications satellite is equipped with ten Ku-band communication transponders, a Gregorian reflector antenna, and two solar panel arrays. The Ku-band communication capability offers improved satellite uplink and downlink signals compared to C-band transponders. It facilitates cross-connectivity between airbases … WebThe procedure is demonstrated by designing both an offset Cassegrain and an offset Gregorian antenna, and is validated by analyzing their radiation patterns using physical optics surface current integration on both the main and subreflectors.< > Published in: IEEE Transactions on Antennas and Propagation ( Volume: 42 , Issue: 8 , August 1994 )
