Title: DUAL-POLARIZED ANTENNA RADIATING UNIT AND DUAL-POLARIZED ANTENNA ARRAY
Abstract:
Disclosed are a dual-polarized antenna radiating unit and a dual-polarized antenna array. The antenna radiating unit comprises two supporting members that intersect each other, a radiating surface located on one end of the supporting members and comprising four slots, and a feed network. The feed network comprises a power dividing part fixed at least on one supporting member. The power dividing part comprises a first main feed fixed on the supporting member, and two branching feeds branched from the first main feed, wherein the two branching feeds respectively extend to two opposite slots on the radiating surface for feeding. The antenna array comprises at least an antenna radiating unit. Various antenna arrays such as a multi-frequency multi-column antenna array and a single-column antenna array can be implemented. The present invention effectively solves problems of overlarge size and complex feed of existing dual-polarized antennas, and implements height reduction and thinning of antennas. Moreover, the simple feed approach avoids the presence of crossed jumpers.
