First Claim
1. An antenna assembly comprising:
- a main reflector;
a subreflector spaced from said main reflector and comprising 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 adjacent said main reflector and directed toward said subreflector, said first antenna feed for the first frequency band; and
second and third antenna feeds arranged in a coaxial relationship and directed toward said main reflector with said subreflector therebetween, said second and third antenna feeds for the second and third frequencies, respectively.

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.

21. A method for making an antenna assembly comprising:
-
positioning a subreflector spaced from a main reflector, the subreflector comprising 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; positioning a first antenna feed adjacent the main reflector so as to be directed toward the subreflector, the first antenna feed for the first frequency band; and positioning second and third antenna feeds arranged in a coaxial relationship so as to be directed toward the main reflector with the subreflector therebetween, the second and third antenna feeds for the second and third frequencies, respectively. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)
