Abstract

The invention provides a base station antenna and base station radio frequency equipment. The base station antenna comprises an antenna unit, wherein the antenna unit comprises an electric dipole, a magnetic dipole, a feeder and a resonance plate, wherein the electric dipole comprises N radiation plates in a center symmetric mode, each radiation plate is provided with a wave trap structure, the Nis an even number greater than 4, the magnetic dipole comprises a short circuit wall which is in ground connection and is arranged at a first side of the plane of the electric dipole, the short circuit wall is coupled with the radiation patches, the feeder comprises N / 2 reversed-U-shaped feed probes laminated at the symmetric center of the electric dipole, each feed probe is coupled with the electric dipole, two end portions of each feed probe respectively extend from the electric dipole plane to the first side, and the resonant plate is arranged in the enclosed space of the reversed-U-shapedfeed probes. The base station antenna is advantaged in that integral antenna frequency band translation is carried out, height of the antenna is reduced, the antenna volume is substantially reduced, low profile miniaturization of the antenna is realized, and antenna manufacturing cost is further reduced.

Description

technical field [0001] The invention belongs to the technical field of antennas, and in particular relates to a base station antenna and base station radio frequency equipment applicable to the fifth generation communication system. Background technique [0002] In modern mobile communication systems, multi-polarization technology has attracted a large part of research attention because of its various electrical characteristics and other numerous advantages. In commercial and industrial applications, multi-polarized antennas are commonly used in base station antennas because they can reduce multipath transmission effects and increase channel capacity. In addition, based on the multi-frequency requirements of 2G, 3G, 4G, and 5G, dual-polarized antennas with small size and wide frequency bandwidth are particularly needed. However, the above-mentioned characteristics are still a big challenge for researchers due to various limitations of miniaturization and broadband. [0003...
