Base station antennas include an externally accessible active antenna module releasably coupled to a rear of the housing. The base station antenna housing has a passive antenna assembly that cooperates with the active antenna module.

A method for providing frequency selective surface zoning includes selecting a location for positioning a frequency selective surface (FSS) panel along a support arm of a reflector antenna system, and positioning a second feed horn on the support arm on an opposite side of the FSS panel. A number of unit cells are used to populate the FSS panel, and metallic patterns are formed on each unit cell. Multiple zones are subsequently defined on the surface of the FSS panel. Each zone is optimized for a predetermined range of incident angles.

There is disclosed an electronic device comprising a front surface including a display screen and a non-metallic bezel surrounding the display screen, and a metallic rear surface. A cavity is defined between the rear surface and the bezel of the front surface along at least a portion of the bezel. The electronic device further comprises a conductive radiating element and a conductive ground plane. The conductive radiating element is mounted in or adjacent to the cavity so as to face the non-metallic bezel in a first direction towards the front surface, and to face the cavity in a second direction towards the rear surface. The conductive radiating element is connected to the conductive ground plane and is additionally connected to the metallic rear surface. The conductive radiating element is configured for excitation by an RF feed, and the cavity serves as a reflector to direct RF signals through the bezel.

An antenna element with a filtering function, a filtering radiation unit, and an antenna. The antenna element is tubular, with a spiral slit arranged around the periphery of the tubular antenna element and extending in an axial direction. The filtering radiation unit includes a support column, and an upper part of the support column is electrically connected to at least one antenna element. The antenna includes a reflecting plate, and at least one filtering radiation unit is fixedly arranged on the reflecting plate. The antenna element with a filtering function has functions of radiating signals and suppressing interference simultaneously. The filtering radiation unit can cooperate with a high-frequency radiation element during use to achieve the aim of radiating a high-frequency signal and a low-frequency signal simultaneously. The antenna is good in performance, small in size, and high in integration degree.

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.
