    Abstract: A base station antenna includes: a plurality of reflector panels; a plurality of printed circuit boards (PCBs), each of the circuit boards mounted on a respective one of the reflector panels; a plurality of radiating elements mounted on each of the PCBs, wherein the PCBs and the radiating elements are configured and arranged so that the base station antenna receives and transmits radio frequency signals in a first frequency band and a second frequency band; first and second wiper members pivotally mounted on each PCB at respective first and second pivots, the first and second wiper members being configured such that pivotal movement of the first and second wiper members induce downtilt angle adjustment in the radiating elements that transmit and receive signals in first frequency band; third and fourth wiper members pivotally mounted on each PCB at respective third and fourth pivots, the third and fourth wiper members being configured such that pivotal movement of the third and fourth wiper members induce downtilt angle adjustment in the radiating elements that transmit and receive signals in a second frequency band; and a phase shifter linkage comprising a first carrier member and a second carrier member fixed relative to the first carrier member, the first carrier member engaging the first and second wiper members and the second carrier member engaging the third and fourth wiper members. Actuation of the phase shifter linkage causes the first carrier member and the second carrier member to move in concert relative to the PCBs, so that downtilt angle adjustment of the first frequency band equals downtilt adjustment of the second frequency band.

    Abstract: A twin beam base station antenna includes a first array that has a plurality of columns of first frequency band radiating elements, the first array configured to form a first antenna beam that provides coverage throughout a first sub-sector of a three-sector base station. The radiating elements in a first of the columns in the first array have a first azimuth boresight pointing direction and the radiating elements in a second of the columns in the first array have a second azimuth boresight pointing direction that is offset from the first azimuth boresight pointing direction by at least 10°. The radiating elements in the second of the columns in the first array are electrically steered.

    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.
