Abstract: A filter unit comprises a resonant cavity filter that includes a metal housing having an opening therein and a spring-biased contact that extends through the opening in the metal housing to contact a port of the resonant cavity filter. The spring-biased contact may be a pogo pin connector assembly. The metal housing may include an internal chamber having a first open end that is defined by the opening, and the pogo pin connector assembly may extend through at least a portion of the internal chamber.

Abstract: Base station antennas are provided. A base station antenna includes a plurality of arrays of radiating elements. The antenna includes a downlink radio frequency (RF) feed network that is configured to filter downlink portions of different frequency bands and that couples the filtered downlink portions of the different frequency bands to the arrays. Moreover, the antenna includes an uplink RF feed network that couples uplink portions of the different frequency bands to the arrays and that is separate from the downlink RF feed network.

Abstract: An exemplary antenna system has first and second antenna elements, where a diplexer is connected to each second element. First phase shifters are connected to the first elements and to the diplexers, and second phase shifters are connected to the diplexers, but not to the first elements. Either a different bandpass filter is connected to the first and second phase shifters or a single multiplexer is connected to all phase shifters. The antenna system can be used to support communications over first and second sub-bands with independent beam tilts and equivalent beamwidths, where all of the elements are used for the first sub-band, and the second elements, but not the first elements, are used for the second sub-band. Each first element is separated from an adjacent element by a first distance, and each second element is separated from an adjacent element by a second distance different from the first distance.

Abstract: A band-stop filter comprises: a housing having a top wall, a bottom wall and at least one side wall, the housing defining an internal cavity; a signal input port and a signal output port that are respectively disposed on one of the at least one side wall; a resonating element that is disposed in the internal cavity and includes a top, a bottom, and a side; and a transmission line that is disposed in the internal cavity and coupled between the signal input port and the signal output port, the transmission line comprising a coupling section that is coupled to the resonating element, wherein the coupling section is configured to surround more than half of the side of the resonating element and not directly contact the housing and the resonating element.
