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 reflective for a first frequency band and transmissive for both a second frequency band and a third frequency band. A first antenna feed is adjacent the main reflector and is directed toward the subreflector. The first antenna feed is for the first frequency band. The second and third antenna feeds are arranged in a coaxial relationship and are directed toward the main reflector with the subreflector therebetween. The second and third antenna feeds are for the second and third frequencies, respectively.
