Assembly transmission assembly of phase shifters and base station antenna

Abstract

The invention relates to an assembly transmission assembly of phase shifters and a base station antenna; the two phase shifters which are vertically stacked are mounted in an area formed by enclosing of two clamping arms, a cross beam and two connecting arms in the process of the assembly of the two phase shifters which are vertically stacked; the two phase shifters which are arranged in an up-and-down overlapping manner can be combined together; a first connecting piece is connected with two first pull rods, and a second connecting piece is connected with two second pull rods; when the first connecting piece acts, the first connecting piece can synchronously drive the first pull rods of the two phase shifters to act, and the electric inclination angles of the phase shifters on one frequency band can be adjusted; and when the second connecting piece synchronously drives the second pull rods of the two phase shifters to act, the electric inclination angles of the phase shifters on the other frequency band can be adjusted. Compared with a traditional assembling transmission mode of the phase shifters, the occupied space of the phase shifters in the length direction can be reduced, so that cable layout and wiring can be facilitated, the cost can be reduced, and the intermodulation stability can be improved favourably.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to an assembled transmission assembly of a phase shifter and a base station antenna. Background technique [0002] In the mobile communication network coverage, the base station antenna is one of the key equipment of the coverage network, and the phase shifter is the core component of the electric base station antenna. The performance of the phase shifter directly determines the performance of the base station antenna, which in turn affects the to network coverage quality. [0003] With the rapid development of society, the communication industry has ushered in the fifth generation communication system, and has become the mainstream of the industry development. In the field of traditional base station antennas, phase shifters of different frequency bands usually have different phase shifter cavities. When the metal cavity of the phase shifter is longer, it will occupy more reflect...

AI Technical Summary

Problems solved by technology

In the field of traditional base station antennas, phase shifters of different frequency bands usually have different phase shifter cavities. When the metal cavity of the phase shifter is longer, it will occupy more reflector space, which is not conducive to the cable layout of the base station antenna. At the same time, the length of the reflector and radome used in conjunction with it is relatively long, resulting in high cost. In addition, the stability of intermodulation is poor
