Problems solved by technology

[0007] The main disadvantage of existing base station antennas is that the implementation form and assembly process are complicated, and metal die-casting vibrators are mostly used for implementation, which requires a complex feed network, such as the need to use 4 coaxial cables to achieve feed
Even if the broadband antenn...

Abstract

The invention discloses a low-profile small-scale dual-polarized base station antenna. The low-profile small-scale dual-polarized base station antenna comprises an antenna housing, a plurality of oscillator components, a power distribution plate, two inner side metal baffles and a reflection plate. The antenna housing covers the reflection plate, and the oscillator components, the power distribution plate and the inner side metal baffles are positioned inside the antenna housing. Two sides of the reflection plate are provided with vertical flanges, and the power distribution plate is positioned on the front or back surface of the reflection plate and fixedly connected with the reflection plate. Each oscillator component comprises a radiation plate and a supporting device, and each radiation plate is fixed to the power distribution plate through the corresponding supporting device. The two inner side metal baffles are symmetrical relative to the oscillator components and fixed to the reflection plate. The low-profile small-scale dual-polarized base station antenna has the advantages of ultra wideband, high gain, high efficiency, high cross polarization ratio, high front-to-back ratio, high isolation and the like.

Description

technical field [0001] The invention mainly relates to the technical field of antennas, in particular to a low-profile small dual-polarization base station antenna. Background technique [0002] The base station antenna is the electrical bridge between the user terminal and the base station in the air in the mobile communication system. It is the most critical component in the entire antenna feeder system. The quality of the base station antenna directly affects the communication quality. [0003] According to the application occasion, the base station antenna can be roughly divided into two categories: [0004] One is the large-scale macro base station antennas erected on high-rise buildings and iron towers, which are characterized by a relatively large number of units, relatively high gain, precise beam forming and user tracking, and large power capacity for wide-area coverage; [0005] The other type is small and micro base station antennas, which are characterized by a ...
