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.

Cavity phase shifter and base station antenna

Base station antennas, and components for base station antennas, such as reflectors, feeder components, frames, and column components. A base station antenna may include a reflector; a first radiator located at the front side of the reflector; mutually parallel first and second ground plates extending backward from the reflector and basically perpendicular to the reflector; and a first conductor strip extending between the first and second ground plates and configured to feed power to the first radiator. The first conductor strip and the first and second ground plates may be configured as a first stripline transmission line. The reflector and the first and second ground plates may be configured as one piece so that the reflector is grounded via the first and second ground plates without soldering.

Container

A container () comprising one or more walls () and a base () defining an enclosure for storing and displaying one or more items (). A locking tab () is defined in each side wall () and corresponding locking slots () are defined in the base (). The locking tabs () each define an undercut (). The container () can be mounted on top of a further container () to form a modular display device by inserting the locking tabs () of the further container into the locking slots () and sliding the container forwardly to engage the base () in the undercuts. The modular display device (, FIG.) may also include a stand for supporting one or more containers at an angle on a horizontal surface and a header.
