Abstract

The present application provides a phase shifter comprising a feed unit, a coupling element and a first phase shifting section. The feeding unit is electrically connected to the coupling element, and the coupling element is electrically connected to the first phase shifting section. The first phase shifting section comprises a substrate and two layers of slow wave microstrip lines. The two layers of slow wave microstrip lines have the same structure, and are arranged in mirror symmetry on the front and back surfaces of the substrate. The two layers of slow wave microstrip lines are electrically connected to each other through a plurality of metal vias. The coupling element is moved relative to the two layers of slow wave microstrip lines of the first phase shifting section to change the phase of the signal flowing through the phase shifter. Also provided in the present application is an antenna. The phase shifter provided by the present application has the advantages of small size, good scalability, low cost and simple assembly.

Description

technical field [0001] The present application relates to the field of antennas, and in particular, to a phase shifter with filter elements and an antenna applicable to the antenna. Background technique [0002] The phase shifter is the core component of the electrical adjustment base station antenna, and it plays a major role in the electrical adjustment of the antenna's pattern. The phase shifter realizes the electrical adjustment of the antenna pattern by changing the phase of the arriving antenna unit, so as to achieve the purpose of remote control and adjustment of the network coverage area under different circumstances. The current base station antenna phase shifter not only needs to have the function of precisely changing the phase, but also has the function of power distribution. The overall cost of the base station antenna. Therefore, how to design a phase shifter that is small in size, easy to expand, low in cost and easy to assemble is a subject of research in t...
