Abstract: 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.

Abstract: 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.

Abstract: The present invention relates to an actuator assembly for a base station antenna. The actuator assembly includes a plurality of actuators mounted side by side, a drive shaft, a drive gear configured to be axially movable relative to the drive shaft, and a moving device configured to axially move the drive gear relative to the drive shaft. Each actuator has a driven gear and an actuator element that is in transmission connection with the driven gear. The drive gear is configured for axial movement relative to the drive shaft, so as to engage with or disengage from the driven gear of any one of the actuators and configured to drive the one driven gear in engagement with the drive gear. The actuator assembly has a simple structure, a low height, a favorable PIM performance, and is expandable flexibly.
