Abstract

The invention is applicable to the field of mobile communication base stations and radio-frequency techniques and provides a phase shifter. The phase shifter comprises a feed network, an upper substrate, a phase shifting media device and a lower substrate, wherein the feed network is arranged between the upper substrate and the phase shifting media device, the upper substrate is arranged above the feed network, the phase shifting media device is arranged between the feed network and the lower substrate, the phase shifting media device and the feed network form a strip-shaped linear structure, and the lower substrate is arranged below the phase shifting media device. Manufacturing cost of the phase shifter is reduced, and performance of the phase shifter is improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a phase shifter. Background technique [0002] In mobile communication coverage, the downtilt angle of the antenna can be adjusted in a variety of ways, such as mechanical downtilt and electric downtilt. In recent years, with the rapid increase in the number of end users, the distribution of users has become dense and changes over time. Due to the characteristics of different time points and changes in factors such as holidays and festivals, the status of the base station has significant changes, sometimes the utilization rate is low, and sometimes the load is full. On this basis, electronically adjustable antennas are widely used in communication base stations instead of conventional mechanical downtilt antennas. The electric adjustable antenna means that there are one or more phase shifters inside the antenna, and the phase shifters move up and down to change the length ...
