Abstract

The invention provides a broadband coupled dual-polarized antenna vibrator, and belongs to the technical field of communication base station antenna manufacture. The broadband coupled dual-polarized antenna vibrator comprises a reflecting board, a medium substrate, a support seat and a feed sheet. A vibrator body is shaped by die-casting a metal and is of an I-shaped vibrator structure, wherein the medium substrate is arranged at the upper end of the I-shaped vibrator structure; a surface radiation structure is arranged at the upper end of the medium substrate; the support seat is arranged in the middle of the medium substrate; and the reflecting board is arranged at the lower end of the medium substrate. The manufacturing method for the broadband coupled dual-polarized antenna vibrator comprises the following steps: (1) preparing a die of each component of the vibrator body; (2) die-casting the die of each component prepared by the step (1) for moulding; and (3) assembling the components moulded by die-casting by the step (2) by welding and by bolts. The broadband coupled dual-polarized antenna vibrator has the advantages of gain, cross polarization ratio, front-to-back ratio, side-lobe energy ratio, dual polarization overlap ratio, simple structure, few constituent parts, and easy production and assembly.

Description

technical field [0001] The invention relates to the field of mobile communication base station antennas, in particular to the technical field of manufacturing broadband dual-polarization communication base station antennas. technical background [0002] The base station antenna is an essential part of the entire communication network, and all communication systems require the antenna as an important antenna feeder system. With the development of mobile communication technology, the index requirements of base station antennas are also gradually developing. As the most basic component element of the antenna, the improvement of the performance of the radiation unit is the most effective means to meet the requirements of the communication industry for the antenna. The radiation unit of the traditional base station antenna is usually implemented by two orthogonal half-wave arrays with a balancer, but the gain, cross-polarization ratio, front-to-back ratio, sidelobe energy ratio,...
