Description

Technical Field

[0002] Dual-polarized antenna is a new type of antenna technology, which combines two mutually orthogonal antennas with polarization directions of +45° and -45° and works in duplex mode at the same time. Therefore, its most prominent advantage is to save the number of antennas in a single directional base station. Dual-polarized antenna has the advantages of electrically adjustable antenna. Using dual-polarized antenna in mobile communication network can reduce call loss, reduce interference and improve the service quality of the whole network, just like electrically adjustable antenna.

[0003] The existing dual-polarized antenna is usually directly mounted on a pole, and the antenna is located in mid-air. When birds fly over or rest directly on the antenna, it may affect the normal operation of the antenna or even damage the antenna, which cannot meet the production needs. Therefore, a dual-polarized BD2B3 anti-interference antenna unit is proposed to solve the above problems. Utility Model Content
