ABSTRACT:
A dual-band feed for use in a microwave reflector antenna. The feed for one band is a an open-ended waveguide or a horn-type feed and the feed for the second band is a helix antenna. The wave-guide or horn-type antenna is located inside of the helix antenna and concentric with the helix antenna so as to cause the beams from the two feeds that are reflected by the reflector to be directed in the same direction.
