Abstract

The invention provides a high-frequency radiator, a multi-frequency array antenna and a base station. The high-frequency radiator comprises two single-polarization radiators of + / - 45 degrees; the single-polarization radiator comprises a radiation arm, a Balun, a feed circuit, a filter and a ground layer. The radiation arm is electrically connected with the Balun; the feed circuit and the Balun are respectively arranged on two surfaces of the first dielectric plate which is vertically arranged; the ground layer is arranged on the downward surface of the second dielectric plate which is horizontally arranged; the first dielectric plate is vertically arranged on the second dielectric plate; the filter comprises a capacitor branch circuit and an inductor branch circuit, wherein the inductor branch circuit is arranged on the same surface of the first dielectric plate as the Balun, the inductor branch circuit is electrically connected with the Balun and the ground layer, and the capacitor branch circuit is coupled with the ground layer; the feed circuit is used for feeding the high-frequency radiator; the filter is used for weakening the influence of the high-frequency radiator on the low-frequency radiator. According to the invention, the problem of common-mode resonance of the high-frequency radiator is solved, the bandwidth of the antenna is not influenced, and the processing cost is low.

Description

technical field [0001] The present application relates to antenna technology, in particular to a high-frequency radiator, a multi-frequency array antenna and a base station. Background technique [0002] With the development of mobile communication systems, base station antennas need to implement multi-frequency and multi-polarization to meet the common needs of multiple operators. However, in the implementation of conventional multi-frequency antennas, the width dimension must be very large to meet the index requirements. Once the width dimension is reduced, the electromagnetic wave will generate common mode resonance in the high-frequency radiator when it is coupled from the low-frequency radiator to the high-frequency radiator. , causing the low-frequency indicators to deteriorate significantly. [0003] At present, the method of suppressing the common-mode resonance of the high-frequency radiator in the low-frequency operating frequency band in the multi-frequency anten...
