Abstract

The present invention discloses a dual-frequency / dual-polarized base station antenna with parallel double line feed. The antenna comprises a radiation patch layer, four inverted-L-shaped metal strips which are perpendicular to the radiation patch layer and are orthogonal to each other, and a feeding layer, from top to bottom in turn, wherein the radiation patch layer comprises a first metal covering layer and a first dielectric layer, the first metal covering layer is square-shaped with each corner being cut off by the same isosceles right triangle, the four inverted-L-shaped metal strips serve as extension of the feeding layer and perform coupled feeding to the radiation patch layer, and the feeding layer comprises a first metal feeder line layer, a second dielectric layer, a metal floor layer, a third dielectric layer and a second metal feeder line layer. The advantages and beneficial effects are that the base station antenna is small in size, a feed network is simple in structure and the bandwidth is larger.

Description

technical field [0001] The invention belongs to the technical field of antennas, and relates to a dual-frequency dual-polarization base station antenna fed by parallel dual wires. Background technique [0002] With the popularization of mobile communication equipment, there are higher requirements for the design of mobile base stations, such as compatibility with multiple communication protocols, saving resources for building multiple base stations, and small size and strong concealment. As a part of the larger volume, the antenna puts forward higher requirements for its design, usually including compatibility with multiple communication frequency bands, polarization isolation of sending and receiving signals on the same antenna, and smaller size. [0003] Based on this purpose, the design of the base station antenna needs to have a certain working bandwidth, ±45° dual-linear polarization, wider beam, better front-to-back ratio, and cross-polarization suppression. Interfere...
