A method for upgrading a dual-band antenna assembly to a tri-band antenna assembly is provided. The dual-band antenna assembly includes a main reflector, and first and second antenna feeds arranged in a coaxial relationship and directed toward the main reflector. The first and second antenna feeds are for first and second frequency bands, respectively. The method includes positioning a third antenna feed through a medial opening in a center of the main reflector, with the third antenna feed directed towards the first and second antenna feeds. The third antenna feed is for a third frequency band. A subreflector is positioned between the main reflector and the first and second antenna feeds. The subreflector includes a frequency selective surface (FSS) material that is reflective for the third frequency band and transmissive for both the first and second frequency bands.

A communications system may include a first active circuit device and a waveguide coupled to the first active circuit device. The waveguide may include a plurality of passive optical devices spaced apart from one another and arranged along an optical path, and an interconnect structure interconnecting the passive optical devices and integrally formed as a unitary body with the passive optical devices. Furthermore, the interconnect structure may have an opening therethrough aligned with the optical path.

Folded optics reflector system includes a hoop assembly configured to expand between a collapsed configuration and an expanded configuration to define a circumferential hoop. A mesh reflector surface is secured to the hoop assembly such that when the hoop assembly is in the expanded configuration, the reflector surface is expanded to a shape that is configured to concentrate RF energy in a desired pattern. The system also includes a mast assembly comprised of an extendible boom. The hoop assembly is secured by a plurality of cords relative to a top and bottom portion of the boom, whereby upon extension of the boom to a deployed condition, the hoop assembly is supported by the boom. A subreflector is disposed at the top portion of the boom.

A method for upgrading a dual-band antenna assembly to a tri-band antenna assembly is provided. The dual-band antenna system includes a main reflector, a strut assembly coupled to the main reflector defining an antenna feed receiving area spaced from the main reflector, and a subreflector carried by the strut assembly and also spaced from the main reflector. The subreflector includes a frequency selective surface (FSS) material that is reflective for both a first frequency band and a second frequency band and transmissive for a third frequency band. First and second antenna feeds are arranged in a coaxial relationship adjacent the main reflector and directed toward the subreflector. The first and second antenna feeds are for first and second frequency bands, respectively. The method includes positioning a third antenna feed at the antenna feed receiving area and directed towards the subreflector and the main reflector. The third antenna feed is for the third frequency band.

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.
