Abstract

The invention discloses a dual-polarized antenna radiating unit and a dual-polarized antenna array. The antenna radiating unit comprises two intersected support parts, a radiating surface and a feed network, wherein the radiating surface is located at one end of each support part and comprises four gaps; the feed network comprises a power dividing component which is at least fixed on one support part; the power dividing component comprises a first main feeder fixed on the support parts and two paths of branch feeders divided from the first main feeder; and the two paths of branch feeders extend to two opposite gaps in the radiating surface for feeding respectively. The antenna array comprises at least one antenna radiating unit, so that various antenna arrays of a multi-frequency and multi-column antenna array or a single-column antenna array and the like can be achieved. The dual-polarized antenna radiating unit and the dual-polarized antenna array have the advantages that the problems that an existing dual-polarized antenna is overlarge in size and complicated in feeding are effectively solved; the conditions that the height and the thickness of the antenna are reduced, and the feeding is simple are achieved; and the cross wire jumper is avoided.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a dual-polarization antenna radiation unit and a dual-polarization antenna array. Background technique [0002] With the increasing update of science and technology, mobile communication has come into people's life and plays an important role. Due to the rapid increase in the number of users, the working frequency bands of various mobile communication systems are constantly expanding, which makes the demand for antenna radiation units continue to increase. [0003] In the dual-polarization radiating unit system, people have invested considerable manpower and material resources to carry out extensive and in-depth research. Several dual-polarization antennas have come out, but basically each of them requires a large number of components, otherwise it will be Defects such as low acceptance rates or low frequency bands can occur. In the prior art, for example, CN1418388A disc...
