Problems solved by technology

[0003] However, the above scheme has the following two problems: 1. Too many electronically adjustable antenna driver motors increase the difficulty of consistency and synchronization
2. The application of adapters such as tie rods affects the accuracy of the phase shifter
Especially under the high requirements of amplitude and phase on 5G large-scale multi-channel antennas, the above-mentioned traditional driving methods are more difficult to meet the requirements of antenna amplitude, phase consistency, and high precision

According to the invention, the plurality of phase shifters is driven by fewer motors, the phases of the plurality of phase shifters are synchronously adjusted, and the phase adjustment precision and consistency of the phase shifters are improved.

Description

technical field [0001] The invention relates to a transmission device in a mobile communication antenna, in particular to a phase shifter transmission device. Background technique [0002] The radiation angle of the mobile communication antenna needs to be adjusted according to the change of the main source of the antenna, and the method is to adjust the phase shifter in the antenna by driving the transmission device. The traditional transmission device of the phase shifter is one or more motor drives to drive a single or multiple phase shifters through adapters such as pull rods, so as to change the phase shifter phase of the base station antenna in the mobile communication system and realize the antenna. Electric downtilt adjustment control. [0003] However, the above solution has the following two problems: 1. Too many electrically adjustable antenna driver motors increase the difficulty of consistency and synchronization. 2. The application of adapters such as tie rod...
