Problems solved by technology

[0004] However, the motor used to drive the phase shifter in the traditional transmission device still corresponds to the transmission mechanism of the phase shifter one by one, the number of motors has not been reduced, and the number of drive circuits in the control module has not been reduced as much as the number of motors
If the frequency band of the antenna continues to increase, the structure of the transmission system will be more complex and bulky, which will affect the reliability of the multi-frequency antenna
[0005] The applicant has practiced relevant technical solutions for the above problems, but there is still room for improvement in terms of stable control and simple operation, especially for the situation where one control is more than one, and the improvement space for related structures is still large

Abstract

The invention provides a multi-frequency antenna and a phase shift control mechanism thereof. The mechanism comprises a transmission part, a straight movement mechanism and a turnover mechanism, wherein the straight movement mechanism is used for controlling the transmission part to be switched among a plurality of positions in the axial direction of the transmission part, so that the transmission part is connected with any one of the plurality of frequency-selecting phase-shifting units at two of the positions; the turnover mechanism is used for controlling the transmission part to rotate in the circumferential direction; for each connected frequency-selecting phase-shifting unit, at a first position, the transmission part is linked with a driven gear in the frequency-selecting phase-shifting unit to linearly operate so as to be suitable for being aligned with any one of a plurality of phase modulation control parts; and at the second position, the transmission part is linked with the driven gear so as to be suitable for controlling the aligned phase modulation control part to shift the phase. By means of the switching control mechanism, selective phase shifting control over the multiple unitized frequency-selecting phase-shifting units can be achieved, and stable and controllable phase shifting control is achieved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular, the present invention relates to a multi-frequency antenna and a phase-shift control mechanism thereof. Background technique [0002] With the increasing number of mobile communication terminal users, the demand for network capacity of sites in the mobile cellular network is increasing. At the same time, it is required to minimize the interference between different sites or even between different sectors of the same site, that is, to realize the network Maximize capacity and minimize interference. To achieve this purpose, it is usually achieved by adjusting the downtilt angle of the antenna beam on the station. [0003] Among the two methods of adjusting beam downtilt, mechanical downtilt and electronic downtilt, electronic downtilt has obvious advantages and is the current mainstream and future development trend. Electric downtilt control is mainly divided into two...
