摘要： Base station antennas include a reflector, a first linear array of radiating elements extending forwardly from the reflector, the radiating elements in the first linear array configured to operate in a first frequency band, and a second linear array of radiating elements extending forwardly from the reflector, the radiating elements in the second linear array configured to operate in the first frequency band. These antennas further include an isolation wall that is positioned in between the first linear array of radiating elements and the second linear array of radiating elements. This isolation wall comprises at least one partially reflective surface that is configured to reflect, on average as a function of frequency, between 20% and 80% of incident radiation in the first frequency band.

摘要： 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.

摘要： Base station antennas are provided herein. A base station antenna includes a plurality of vertical columns of low-band radiating elements configured to transmit RF signals in a first frequency band. The base station antenna also includes a plurality of vertical columns of high-band radiating elements configured to transmit RF signals in a second frequency band that is higher than the first frequency band. The vertical columns of high-band radiating elements extend in parallel with the vertical columns of low-band radiating elements in a vertical direction.

摘要： The present disclosure has disclosed a base station antenna comprising an antenna core provided with an antenna base at the bottom thereof and provided with an antenna bracket at the top thereof; and a radome sleeved over the antenna core. The radome includes a top wall and a side wall that protrudes downward from the top wall. The antenna core and the radome are connected together by a fixed connection portion located near a bottom end of the radome and a floating connection portion located near a top end of the radome. The floating connection portion fixes a position of the radome on the antenna core in a horizontal direction and allows the radome to float relative to the antenna core in a vertical direction by cooperating the antenna bracket with the top wall of the radome or the side wall at the top of the radome. The base station antenna solves the problem of a tensile force between the antenna core and the radome resulting from the temperature change, thereby improving the performance parameters such as PIM of the base station antenna.

摘要： Base station antennas comprise a planar reflector, a radiating element mounted to extend forwardly from the planar reflector, the radiating element including a dipole that comprises an inner dipole arm and an outer dipole arm, and a radome having a front wall, a side wall and a curved front transition wall that connects the front wall to the side wall. A distal end of the outer dipole arm is closer to the planar reflector than is a base of the outer dipole arm, and an overlap portion of the outer dipole arm overlaps the curved front transition wall. A largest minimum distance between any point on a front surface of the overlap portion of the outer dipole arm and the radome is less than twice a smallest minimum distance between any point on the front surface of the overlap portion of the outer dipole arm and the radome.
