Abstract

According to a phase shift measuring device provided by the invention, at least two phase shift transmission mechanisms are arranged in the circumferential direction of a metering shaft, the phase shift transmission mechanisms execute axial movement through movable parts of the phase shift transmission mechanisms so as to control the phase shift of the corresponding single frequency band in a multi-frequency antenna in a linkage manner, after the movable parts move for a certain distance to complete the signal phase shift of the single frequency band, the metering shaft is pulled to enable its protruding ribs to abut against the movable parts, data of the metering shaft is read, the displacement amount of the movable parts corresponds to the corresponding phase shift, and therefore the phase shift amount of the single frequency band controlled by the corresponding phase shift transmission mechanism is obtained. The phase shift measuring device provided by the invention is simple in structure and easy to operate. The invention further provides the multi-frequency antenna comprising the phase shift measuring device.

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 measuring device thereof. Background technique [0002] Since the development of mobile communication, it has entered the 5G era, and the requirements for communication quality are getting higher and higher. The antenna is the front-end equipment of the communication system, and its performance is particularly important to the communication quality. The phase shifter is one of the core modules of the base station's electronically adjustable antenna. In practical applications, the electrically adjustable antenna needs to shift the phase of the transmitted signal to adjust the tilt angle of the beam of the antenna. The process of phase shifting is a process of high-precision control, and the precise structure plays a key role in precise phase shifting. Similarly, accurate measurement of the a...
