Abstract
An antenna feed system includes a plurality of RF horn antennas () for operating on a plurality of RF frequency bands. A first one of the feed horns () can have a boresight axis and is configured for operating at a first one of the frequency bands. A second one of the feed horns () is positioned coaxially within the first one of the feed horns () and is configured for operating at least at a second one of the frequency bands. Further, the first one of the feed horns () is a corrugated horn that has a plurality of corrugations () formed on an interior surface defining a profile. The profile extends substantially from a throat () of the first feed horn and along a tapered portion of the first feed horn. The profile substantially minimizes an interaction of the corrugations with the second feed horn.
