Problems solved by technology

Its limitation is that the bracket attached to the antenna FPC needs to reserve a slot for the welding of the feeder pin and the ground pin in the later stage, so at least one direction of the antenna cannot be arbitrarily set with suspended metal traces, which limits the flexibility of the antenna's out-of-roundness debugging , so that the antenna cannot obtain better out-of-roundness

Abstract

The invention discloses a 5G base station antenna housing which comprises an antenna cover body and a metal wire. The antenna cover body is used for covering the antenna unit; the metal wire is arranged at the position, corresponding to the antenna unit, of the antenna cover body, the distance between the metal wire and the antenna unit is smaller than 1 / 4 of the working wavelength of the antenna unit, the radiation intensity of the antenna can be affected through the metal wire, debugging of the out-of-roundness of the antenna is achieved, and the problem in the prior art that the metal wire is directly arranged on the antenna wire is prevented. Instead, the metal wire is arranged on the antenna cover body, the antenna cover body is used for covering the antenna unit, the arrangement position of the metal wire is prevented from being affected by the antenna structure, the metal wire can be arranged in any direction of the antenna unit, and therefore the out-of-roundness of the antenna can be debugged more flexibly; therefore, the antenna has a good out-of-roundness index.

Description

technical field [0001] The invention relates to the technical field of 5G communication, in particular to a radome for a 5G base station. Background technique [0002] With the development of mobile communication in the 5G era, its operating spectrum has also expanded from Sub 3GHz to Sub 6GHz. The newly expanded frequency band from 3.3GHz to 5GHz has higher frequencies and shorter wavelengths, which brings greater challenges to the design of out-of-roundness indicators for small base station antennas. [0003] Small base station antennas are usually implemented using a FPC (Flexible Printed Circuit board, flexible printed circuit board) process. Usually, suspended metal traces are designed near the antenna traces to change the antenna pattern and optimize the out-of-roundness index. Its limitation is that the bracket attached to the antenna FPC needs to reserve a slot for the welding of the feeder pin and the ground pin in the later stage, so at least one direction of the ...
