Abstract
An antenna assembly includes a main reflector, and a subreflector spaced from the main reflector. The subreflector includes a frequency selective surface (FSS) material that is transmissive for a first frequency band and reflective for both a second frequency band and a third frequency band. A first antenna feed is adjacent the subreflector and is directed toward the main reflector. The first antenna feed is for the first frequency band. Second and third antenna feeds are arranged in a coaxial relationship adjacent the main reflector and are directed toward the subreflector. The second and third antenna feeds are for the second and third frequency bands, respectively.
