  • Patent number: 11205836
    Abstract: An antenna array module includes at least two antenna units mounted on a surface of a feed network circuit board with two power division circuits, and a filter mounted on a surface of the feed network circuit board with two coupling circuits. Each power division circuit includes an input end and a plurality of output ends. One power division circuit feeds an antenna unit for ?45° polarization, and the other power division circuit feeds an antenna unit for +45° polarization. Each coupling circuit includes a radio frequency input end and an output end, and the output end of the coupling circuit is electrically connected to the input end of the power division circuit. The filter includes at least two output ends that are electrically connected to the radio frequency input end of the coupling circuit. A base station antenna includes a mounting structure and a connection structure.

  • Patent number: 9385432
    Abstract: A wideband dual-polarized radiation element includes two pairs of cross polarized dipoles and baluns which correspondingly feed current to each dipole in a balanced manner. Each dipole includes a pair of unit arms aligned on a top end of the corresponding balun. One end of each unit arm is connected on top of the balun, and the other end of one unit arm is bending inwards to form inward loaded line, and the other unit arm is bending downwards to form downward loaded line. An antenna includes a metal reflector and at least one wideband dual polarized radiation element, which has excellent radiation and polarization performance.
