## Abstract

An improved microwave system. Certain embodiments include a radio transceiver, an antenna, an antenna feed mechanism, and the necessary RF cabling to connect these elements. In the present invention, an antenna feed system is described. The antenna feed system may comprise the radio transceiver, which is integrated with the antenna feed mechanism and the antenna conductors. In the exemplary embodiment, the antenna feed assembly further comprises connectivity for a digital signal interface; antenna feed pins, director pins and sub-reflectors. Typically, these elements are located on a printed circuit board and housed in weather proof housing which may be disposed on the feed arm of a parabolic reflectors. Some embodiments may support OSI layer digital communications.

## Claims

### Claim 1

A center fed parabolic microwave system comprising:
an antenna feed system coupled to a parabolic reflector;
the antenna feed system comprised of:
a printed circuit board positioned along an axis of symmetry of the parabolic reflector, with a distal portion of the printed circuit board positioned towards a focal point of the parabolic reflector, while a proximal portion of the printed circuit board positioned away from the focal point of the parabolic reflector;
a plurality of active antenna elements located at the distal portion of the printed circuit board and extending from the axis of symmetry of the parabolic reflector in opposite directions;
a radio transceiver located on the printed circuit board, wherein the radio transceiver is configured to receive a digital signal and generate a radio frequency (RF) signal, said RF signal is coupled to the plurality of active antenna elements; and
a sub-reflector having a concave surface, the sub-reflector positioned distal to the printed circuit board and on the axis of symmetry of the parabolic reflector,
wherein the sub-reflector is configured to reflect radiated energy generated by the plurality of active antenna elements back to the parabolic reflector, and the transceiver includes a client controller that supports OSI layers.
