Coaxial horn antenna system
TLDR
An antenna feed system includes a plurality of RF horn antennas ( 201, 202 ) for operating on a plurality-of-RF frequency bands as discussed by the authors, which can have a boresight axis and is configured for operating at a first one of the frequency bands.Abstract:
An antenna feed system includes a plurality of RF horn antennas ( 201, 202 ) for operating on a plurality of RF frequency bands. A first one of the feed horns ( 202 ) 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 ( 201 ) is positioned coaxially within the first one of the feed horns ( 202 ) and is configured for operating at least at a second one of the frequency bands. Further, the first one of the feed horns ( 202 ) is a corrugated horn that has a plurality of corrugations ( 204 ) formed on an interior surface defining a profile. The profile extends substantially from a throat ( 205 ) 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.read more

Design of conical corrugated feed horns for wide-band high-frequency applications
TL;DR: In this paper, a new analytical procedure for the design of the conical corrugated feed horns used in the millimeter and submillimeter wavelength range was presented, which could achieve wideband singlemode operation and wide-band, low return-loss impedance matching simultaneously.
