Problems solved by technology

However, pointer-type phase shifters generally have the problem that the gap between the pointer and the dielectric plate is too large and uneven due to deformation, which leads to changes in the level amplitude and phase of each port, which in turn affects the downtilt of the electric antenna beam. item indicator

Abstract

The invention discloses a phase shifter. The phase shifter comprises a dielectric slab and a pointer assembly. The pointer assembly is electrically connected with the dielectric slab and can rotate relative to the dielectric slab; the pointer assembly is provided with a hook matched with the edge of the dielectric slab. According to the phase shifter, by arranging the pointer assembly with the hook, the hook can be in matched connection with the edge of the dielectric slab and used for limiting the relative position between the pointer assembly and the dielectric slab, constraining the deformation of the pointer assembly and improving the assembly stability of the pointer assembly and the dielectric slab, thus, the situation that in the related art, as a pointer assembly and a dielectric slab deform, the gap between the pointer assembly and the dielectric slab is too large and not uniform can be avoided, and then the functional stability of the phase shifter can be guranateed.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular, to a phase shifter. Background technique [0002] With the development of mobile communication systems and urban construction, interference between base stations, pilot pollution of communication networks, cross-area coverage, and multipath effects are becoming more and more serious. By adjusting the downtilt angle of the antenna, the network coverage can be effectively enhanced and optimized. In related technologies, the ways to adjust the downtilt angle of the antenna include mechanically adjusted downtilt angle and electronically adjusted downtilt angle. The mechanically adjusted downtilt angle is to tilt down a certain physical angle when the antenna is installed. angle without changing the physical angle at which the antenna is mounted. Although mechanical adjustment of downtilt angle can improve coverage to a certain extent, there are disadvantages such as the...
