Abstract:
A reflector antenna adapted for use on a mobile platform, comprising:a main reflector having an aperture at its axial center; a subreflector spaced forwardly of said main reflector; a support structure for supporting said subreflector fixedly relative to said main reflector; a feed horn disposed within said aperture such that a first portion of said feedhorn projects forwardly of said main reflector and a second portion of said feedhorn projects rearwardly of said main reflector; and an antenna electronics subsystem for processing at least one of signals sent to or received by said feedhorn, and being disposed closely adjacent said main reflector so as to be disposed exteriorly of said mobile platform, wherein the antenna electronics subsystem comprises: a first antenna signal processing subsystem including a vertical and horizontal polarization signal processing subsystem for processing signals sent to or received by said feedhorn and being disposed closely adjacent said main reflector so as to be disposed exteriorly of said mobile platform; and a second antenna signal processing subsystem including a transmit and receive subsystem in communication with said first antenna signal processing subsystem for processing signals sent to and received from said first antenna signal processing subsystem, and being disposed interiorly of said mobile platform.
