Abstract
A multi-band ring focus antenna system includes a main reflector () that is operable at a plurality spectrally offset frequency bands. A first feed () includes a first feed horn () and a first sub-reflector (), which are positioned spaced apart from each other at respective locations along a boresight axis of the main reflector. The locations are selected so that the first feed horn and the first sub-reflector share a commonly located first phase center (). A second feed () designed for operation on a second RF frequency band includes a second feed horn () and a second sub-reflector (), each positioned at a location along the boresight axis of the main reflector so that they share a commonly located second phase center.
