The present invention relates to a cavity phase shifter with a housing having at least one cavity and a transmission line mounted in the cavity. The transmission line is provided with an input end and an output end. The output end of the transmission line is electrically connected to another transmission line outside the cavity without the aid of a cable.

The phase shifter is mounted rearward of the reflector. The phase shifter includes a printed circuit board that extends perpendicularly to the feed board, and an output end of a transmission line on the printed circuit board is soldered to a trace on the feed board. Thus, the insertion loss associated with the phase cables would be reduced and the gain performance of the antenna can be improved.
