Abstract

The present invention provides a base station antenna and base station radio frequency equipment, including an antenna unit, the antenna unit includes: an electric dipole, including N centrosymmetric radiation pieces, each of the radiation pieces is provided with a notch structure, wherein Said N is an even number greater than 4; the magnetic dipole includes a short-circuit wall for grounding and located on the first side of the plane where the electric dipole is located, and the short-circuit wall is coupled to the radiation sheet; the power feed part includes N/2 Feeding probes in the shape of "ㄇ" and overlapping at the symmetrical center of the electric dipole, each feeding probe part is coupled with the electric dipole, and the two ends of each feeding probe are from where the electric dipole is located. The plane extends toward the first side; and the resonant plate is arranged in the space enclosed by the "ㄇ"-shaped feeding probe. The invention enables the overall translation of the frequency band of the antenna, further reduces the height of the antenna, greatly reduces the volume of the antenna, realizes the miniaturization of the low profile of the antenna, and reduces the production cost of the antenna at the same time.

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...
