Problems solved by technology

In the traditional 65° base station antenna in the horizontal direction, the front-to-back ratio is low, and the directional reception performance is poor. The rear lobe of the antenna may produce over-area coverage, resulting in confusion in the switching relationship and resulting in call drop

Embodiment Construction

[0008] Such as figure 1 As shown, it includes a reflector 1 , a radiation unit 2 and a partition 3 .

[0009] Radiating units 2 are equidistantly distributed along the extending direction of the reflecting plate 1 above, and the radiating unit 2 is composed of four bow-shaped oscillators with +45° polarization and -45° polarization. Both sides of the reflecting plate 1 are bent upwards to form reflecting side walls, and partitions 3 are installed on both sides of the reflecting side walls. The position of the separator 3 in the extending direction of the reflecting plate 1 is between +45° polarization and −45° polarization.

[0010] The height of the partition 3 above the reflective side wall is 20±1mm, and the length of the partition 3 is 25±1mm.

Abstract

The invention relates to a cross-polarization front-to-rear ratio improved base station antenna with a 65-degree horizontal half-power angle. The antenna comprises a reflector and is characterized in that radiating elements are equidistantly distributed on the reflector along the extension direction of the same, each radiating element comprises four positive 45-degree polarized and negative 45-degree polarized bow-shaped oscillators by means of combination, two sides of the reflector are bent upward to form reflecting side walls, isolators are mounted on the two reflecting walls and are positioned between positive 45-degree polarization and negative 45-degree polarization in the extension direction of the reflector. The height of each isolator higher than the reflecting side walls is 20+ / -1mm, and the length of each isolator is 25+ / -1mm. The isolators are mounted on the reflecting side walls to improve the cross-polarization front-to-rear ratio, so that the antenna is high in directional receiving performance, capable of avoiding cross-boundary coverage and not prone to call drop.

Description

technical field [0001] The invention relates to a base station antenna, in particular to a 65° base station antenna in the horizontal direction with improved front-to-back ratio of cross-polarization. Background technique [0002] In the cellular mobile communication system, the antenna is the converter of the circuit signal of the communication equipment and the space radiated electromagnetic wave, and is the bridgehead of the space wireless communication. Therefore, the base station antenna is an important part of the mobile communication system, and its characteristics directly affect the overall performance of the entire wireless network. . In the engineering design of the mobile communication network, base station antennas should be reasonably selected according to actual conditions such as network coverage requirements, traffic distribution, anti-interference requirements, and network service quality. In the traditional horizontal 65° base station antenna, the front-t...
