Abstract

The invention provides an antenna vibrator of a base station, which comprises a vibrator main body and a balun base, and further comprises a feeding line and a folded vibrator. The folded vibrator comprises a radiation plate, wherein the radiation plate is provided with a through hole, and an opening is arranged in the middle position of the radiation plate, the opening is communicated with the through hole, and the opening is connected with a balun base through a feeding line; A plurality of groups of the folded vibrators are arranged on the main body of the vibrator; A plurality of groups offolded vibrators surround the balun base and are uniformly distributed on the vibrator body; The openings of the radiating plates of each group of folded oscillators are connected to the balun base through a feed line. The invention improves the radiation performance of the antenna through the structure, ensures that the radiation unit has the advantage of high gain, and the beam width can be more convergent, meanwhile, the performance such as the front-to-back ratio, the cross polarization ratio and the like are improved. At the same time, the invention reduces the cost of the radiation unitthrough the structure, and realizes the characteristics of convenient assembly and high reliability.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to an antenna dipole for a base station. Background technique [0002] The radiation unit (vibrator) is one of the modules that determine the main radiation indicators of the base station antenna, such as gain, half-power beam width, front-to-back ratio, cross-polarization ratio, etc. At present, the antenna radiation unit of the base station usually adopts opposite dipoles, especially at low frequencies, the bowl-shaped radiation unit is often used. This form has the advantages of high gain, small size, convenient processing and molding, and light weight, but it needs to be fed in the same direction with the same polarization, so one radiation unit needs four feeder cables. In terms of production process, reliability control, and cost There are certain disadvantages. [0003] Secondly, since the dipole is in the form of open-circuit radiation, the radiation current canno...
