Design of a Dual Beam Spacecraft Antenna for Simultaneous Elliptical and Circular Coverages at 11/14 GHz

28 Jun 1989

In order to provide flexible communications service in the K-band (10.95 GHz-12.50 GHz for transmit and 14.00-14.50 GHz for receive) INTELSAT has implemented two fully steerable spot beams on the INTELSAT V and VI spacecraft. On INTELSAT V the West Spot is circular and the East Spot is elliptical, while on INTELSAT VI both beams are elliptical. They are required to be independently steerable and thus cannot be realized by one single reflector antenna but must be implemented using two separate, movable systems.
