Abstract

The invention provides a high-frequency radiation unit which comprises a radiator and a feed panel, the radiator is of a symmetrical structure and comprises two pairs of radiation unit arms and four baluns, the four radiation unit arms and the four baluns are connected in a one-to-one correspondence mode, the two pairs of radiation unit arms are arranged in a polarization orthogonality mode of +/-45 degrees, each pair of radiation unit arms are arranged diagonally, and the feed panel is arranged between the two pairs of radiation unit arms. The four baluns are all connected with the feed panel, each of the four baluns comprises a plurality of sections of impedance conversion branches, the impedances of the plurality of sections of impedance conversion branches are different, the design mode of the high-frequency radiation unit provided by the invention reduces loss, weakens current imbalance caused by feed, improves the cross polarization ratio, further widens the bandwidth, and improves the bandwidth. Therefore, the low-frequency and high-frequency coupling performance of the antenna is improved, and the high-frequency radiation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a high-frequency radiation unit. Background technique [0002] With the rapid development of the communication industry, in recent years, 2G, 3G, 4G and 5G networks have covered a large area, and the requirements for base station antennas are increasing day by day. , low-cost and high-efficiency research has become the mainstream demand of the communication industry. The radiation unit is the basic component of the base station antenna. The length meets the requirements of low cost and light weight. However, this approach often results in a reduction in the low-frequency and high-frequency coupling performance of the antenna, resulting in poor high-frequency performance of the antenna. Contents of the invention [0003] The invention provides a high-frequency radiation unit, which is used to solve the problem of poor performance of the existing antenna radiation unit in the p...
