Radiation unit, antenna and base station

Abstract

The invention provides a radiation unit, an antenna and a base station. The radiation unit comprises two pairs of radiation arms which are arranged in a polarization orthogonality mode; the two pairs of radiation arms are of a central symmetry structure relative to the same central point; and each radiation arm comprises a feed part and a radiation open loop connected with the feed part, wherein the radiation open loop comprises a radiation line, wherein the radiation line is connected in series with at least one filtering unit, and the filtering unit is formed by repeatedly bending a metal wire to form at least one pair of coupling sheets for realizing parallel coupling in different planes. According to the radiation unit, the filtering units are arranged on the radiation arms, and the filtering units are used for counteracting high-frequency current caused by high-frequency signal resonance, so that the problem that the radiation performance is reduced due to mutual coupling when the radiation unit and a high-frequency radiation unit are arranged in a co-array mode is solved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a radiation unit, an antenna configured with the radiation unit, and a base station configured with the antenna. Background technique [0002] With the rapid development of modern mobile communication technology, users' demand for high-capacity and low-latency communication is increasing day by day, so the fifth-generation mobile communication network emerges as the times require. In the process of domestic 5G mobile communication network construction, the coordinated development of multiple network standards is required, such as 5G and 4G networks working at the same time; however, different network standards require different antennas, which causes a sharp increase in the number of antennas on each base station site. It greatly increases the construction and maintenance costs of the antenna base station site, resulting in a waste of antenna environmental re...

Problems solved by technology

In a multi-frequency antenna, the distance between the radiating units is relatively small. When the low-frequency radiating unit and the high-frequency radiating unit are installed with the same aperture, it will inevitably block the high-frequency radiating unit, so that the low-frequency radiating unit will be blocked by the high-frequency radiating unit. The high-frequency signal emitted by the radiation unit is excited to generate high-frequency current, which affects the electrical performance of the multi-frequency antenna, causes problems such as pattern distortion, and then affects the performance of the multi-frequency antenna synthetic beam
