Problems solved by technology

[0004] In order to achieve multi-frequency and miniaturization of the base station antenna, the high-frequency radiation unit and the low-frequency radiation unit in the antenna are placed more compactly, and the high-frequency radiation unit enters the space below the low-frequency radiation unit, and the electromagnetic wave signal radiated by the high-frequency radiation unit will be Received and re-scattered by the low-frequency radiation unit, causing serious distortion of the pattern of the high-frequency radiation unit, resulting in a decrease in the signal coverage quality of the base station antenna, and even interrupting the network of the user's mobile terminal
[0005] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve

Abstract

The invention provides a low-frequency radiation unit. The low-frequency radiation unit comprises a first circuit board, a second circuit board and a bottom board, the first circuit board comprises afirst transverse plate and a first vertical plate, and the second circuit board comprises a second transverse plate and a second vertical plate. The first vertical plate and the second vertical plateare mutually crossed and embedded to form an X-shaped structure, and the lower ends of the first vertical plate and the second vertical plate are fixed on the bottom plate. The first transverse plateand the second transverse plate are respectively provided with two radiation arms in bilateral symmetry to form a dual-polarization radiation unit, each radiation arm comprises a plurality of broadband line segments which are horizontally arranged, and every two adjacent broadband line segments are connected through a bent thin-strip line segment. Feed baluns are arranged on the first vertical plate and the second vertical plate, the lower ends of the feed baluns are electrically connected with the bottom plate, and the upper ends of the feed baluns are electrically connected with the radiation arms. Therefore, the low-frequency radiation unit has a filtering function, and the influence of the low-frequency radiation unit on the high-frequency radiation performance can be effectively reduced when the high-frequency antennas and the low-frequency antennas are nested and arrayed, so that the multi-frequency and miniaturization of the antenna can be realized.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a low-frequency radiation unit and a base station antenna. Background technique [0002] Mobile wireless communication technology is developing rapidly. 2G (GSM), 3G (WCDMA, TD-SCDMA, CDMA2000), 4G (TDD-LTE, FDD-LTE) have been widely integrated into people's daily life, and 5G mobile communication network deployment has also been On the agenda, mobile wireless communication presents a trend of rapid development and the coexistence of multiple technologies. [0003] The base station antenna is the front-end passive device in the mobile wireless communication system. It receives radio information from the user's mobile terminal and sends radio information to the user's mobile terminal at the same time. It is an important information hub in the mobile wireless communication system. At the same time, due to the tense antenna environment, the multi-frequency, miniaturiza...
