Abstract
A broadband satellite antenna for producing a dual-band multiple beam coverage in transmission and reception based on an offset dual-optics configuration that includes a single main parabolic reflector, a hyperbolic sub-reflector, a first transmitting Multiple-Feed-per-Beam feed system, and a second receiving Multiple-Feed-per-Beam feed system. The sub-reflector surface is a Frequency Selective Surface configured to transmit any electromagnetic signals in the higher frequency band and to reflect any electromagnetic signals in the lower frequency band. The Multiple-Feed-per-Beam feed systems are located at the main focal point Fand at the first sub-reflector real focal point F. The eccentricity e of the hyperbolic sub-reflector depends on a ratio between a preset lower frequency fin the lower frequency band Band a preset higher frequency fin the higher frequency band B. The first transmitting Multiple-Feed-per-Beam feed system and the second receiving Multiple-Feed-per-Beam feed system are geometrical scaled versions of each other.
