A Compact Satcom Antenna for X- and Q-Band. (1998)

Abstract
This report describes the development of a Satcom antenna for X- (7.25-7.75 GHz) and Q-band (43-46 GHz). The Q-band antenna is comprised of a dichroic parabolic dish of tripoles making it reflective in Q-band and transparent in X-band. The X-band antenna is made of 24 dipoles in front of a ground plane with the entire X-band array mounted directly behind the Q-band dish. Thus, two bands are covered with the same aperture making the combined array very compact. In addition, planar surfaces we developed are transparent in K-band (19-21GHz) and reflective in Q-band (43-46 GHz). (Author)
