Abstract

The invention provides a phase shifter with an adjustable output mode, which can realize the function of switching the output mode of a conventional antenna in a vertical plane. The phase shifter comprises a fixed dielectric plate on which fixed circuits are arranged; a movable sliding plate arranged on the face, provided with the fixed circuits, of the fixed dielectric plate, wherein a plurality of sliding circuits corresponding to the fixed circuits are arranged on the movable sliding plate, the fixed circuits can be in coupling connection with at least one corresponding sliding circuit to jointly form a phase shift circuit, the movable sliding plate slides relative to the fixed dielectric plate, the sliding circuit coupled with the fixed circuits can be switched, and the phase of an output signal of the phase shift circuit can be adjusted. In addition, the invention further provides an antenna adopting the phase shifter with the adjustable output mode.

Description

technical field [0001] The invention relates to the technical field of mobile communication antennas, in particular to a phase shifter with adjustable output mode and an antenna. Background technique [0002] As an important part of the wireless communication system, the base station antenna plays an important role in the transmission and reception of wireless communication signals, and its performance is directly related to the communication quality of the entire communication system. With the rapid development of mobile communication technology, major technologies such as multi-band and large-scale arrays have been gradually applied to the antennas of electrically adjustable base stations. At the same time, for some special scenarios, more application requirements are put forward for the antenna, such as high-rise coverage, base station signal blindness compensation, etc., and the electronically adjustable antenna needs to be able to switch to the wide beam working mode to...
