Abstract

A microwave system comprises an antenna, antenna feed, a radio transceiver, and appropriate cabling among the aforementioned. Cost, performance and reliability improvements are achieved with further integration of these elements and with design improvements in the antenna feed. One improvement is the integration of the radio transceiver with the antenna feed. This improvement has many benefits including the elimination of RF cables and connectors. Another improvement is the incorporation of parasitic radiators and sub-reflectors as part to of the antenna feed. The entire antenna, including the feed design is optimized with 3D finite element, method (FEM) software and numerical optimization software. Another improvement is the utilization of the digital cable to power the integrated radio transceiver and a center fed parabolic reflector.
