    Abstract: An antenna assembly includes a substrate having front and back surfaces thereon and a plurality of through-holes therein, along with a solder pad on the back surface of the substrate. An input cable is also provided, which is attached to the back surface of the substrate. The input cable includes an outer conductor, which contacts the back surface of the substrate, and an inner conductor, which extends at least partially through a first of the plurality of through-holes and is electrically connected to the solder pad. A metal trace (e.g., 50-ohm trace) is provided on the front surface of the substrate. The metal trace is electrically connected to the solder pad by electrically conductive plating in a second of the plurality of through-holes.

    Abstract: 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 cavity phase shifter also includes a movable element mounted within the cavity. Movement of the movable element is configured to adjust a phase shift experienced by an RF signal that travels between the input end and output end of the transmission line. The cavity phase shifter can be provided in a base station antenna having a reflector; a feed board mounted forwardly of the reflector; and a radiating element extending forwardly from the feed board. 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.
