Abstract: Base station antenna units include a first and second base station antennas that have respective first and second housings. The first housing includes a top end cap and the second housing includes a bottom end cap. A jumper cable that includes a first connector port is mounted in one of the top end cap or the bottom end cap, and a second connector port that is configured to mate with the first connector port is mounted in the other one of the top end cap or the bottom end cap. A longitudinal axis of the first connector port extends in a vertical direction and a longitudinal axis of the second connector port extends in the vertical direction.

Abstract: A phase shifter assembly, suitable for a base station antenna, includes a main printed circuit board with opposing first and second primary sides. The main printed circuit board has a plurality of radio frequency (RF) transmission paths on the first primary side and a plurality of RF transmission paths on the second primary side. The phase shifter assembly also includes a first wiper arm rotatably coupled to the main printed circuit board and electrically coupled to the plurality of transmission paths on the first primary side of the main printed circuit board; and a second wiper arm rotatably coupled to the main printed circuit board and electrically coupled to the plurality of transmission paths on the second primary side of the main printed circuit board. Rearwardly extending phase shifter assemblies that are oriented perpendicular to a plane defined by a reflector within a base station antenna are also provided.

Abstract: Base station antennas include a main module that has a first backplane that includes a first reflector. A vertically-extending array of first radiating elements is mounted to extend forwardly from the first reflector, and at least one first RF port is coupled to the vertically-extending array of first radiating elements. These antennas further include a sub-module that is attached to the first backplane. The sub-module includes a second backplane that has a second reflector that is separate from the first reflector. A vertically-extending array of second radiating elements is mounted to extend forwardly from the second reflector and is transversely spaced-apart from the vertically-extending array of first radiating elements. A plurality of second RF ports are coupled to the vertically-extending array of second radiating elements. The vertically-extending array of first radiating elements and the vertically-extending array of second radiating elements are configured to serve a common sector of a base station.

Abstract: Base station antennas include a RET actuator, a plurality of phase shifters and a plurality of mechanical linkages, where each mechanical linkage is connected between the RET actuator and a respective one or more of the phase shifters. The RET actuator includes a drive element, a rotatable element and a mechanical linkage selection system that is configured to move a selected one of the mechanical linkages into engagement with the drive element. The drive element is configured to move linearly in response to rotation of the rotatable element to move the selected one of the mechanical linkages.
