Abstract
An antenna feed that transmits in a single vertical or horizontal linear polarization at commercial Ka-band while simultaneously receiving both vertical and horizontal polarizations at commercial KU-band is presented. The antenna feed includes a metal feed horn, an integrated corrugated ring filter, an outer conductor disposed coaxially about the feed horn, a hollow inner conductor disposed coaxially within the feed horn and a polyrod disposed within the hollow inner conductor. The antenna feed further includes a PCB having receive channel RF probes, 180-degree hybrid combiners and LNB circuitry. The PCB is surrounded by a housing which is attached to the feed horn.
