Tracking feed for multi-band operation

摘要

An antenna feed system comprises a single horn having corrugations and four evenly spaced waveguide ports on sides of a single one of the corrugations. A combiner network receives signals at approximately 20 GHz from the four waveguide ports and outputs sum and difference output signals. A transducer provides transmit signals at approximately 30 GHz and approximately 44 GHz to a rear end of the single horn.
