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: A radiator assembly for a base station antenna includes two dipoles arranged in a cross-over manner, each dipole including two dipole arms, and two feeding lines, each feeding line being associated with a respective one of the dipoles. Each dipole arm is integrally formed of sheet metal, and includes a radiating surface and a leg projecting from the radiating surface at an angle with the radiating surface, where the leg is electrically grounded.

Abstract: A feed network for use with an antenna array includes at least first and second RF inputs, a combiner network and a beamforming network. In some examples, additional RF inputs are provided. Each RF input corresponds to a sub-band. The first RF input for a first sub-band signal is coupled to a first sub-band parameter control; the second RF input for the second sub-band signal is coupled to a second sub-band parameter control. The combiner network is coupled to the first sub-band parameter control and to the second sub-band parameter control. The combiner network also has at least one output comprising a combination of the first sub-band signal and the second sub-band signal. The beamforming network is coupled to the combiner network and has a plurality of RF outputs. The first and second sub-band parameter controls are independently adjustable. In one example, the beamforming network comprises a Butler matrix.
