Abstract

The invention relates to the technical field of base station antennas, in particular to a cavity medium sliding type phase shifter and a base station antenna, and the cavity medium sliding type phase shifter comprises a phase shifter cavity; a circuit base material arranged in the phase shifter cavity; a phase-shifting circuit which is arranged on the circuit base material, and comprises a power divider network and a phase-shifting branch network located under the power divider network, extending in the left-right direction, and comprising an input port and at least two output ports; a sliding medium which is arranged in the phase shifter cavity and slides relative to the circuit substrate in the left-right direction; and foam which is fixedly arranged on the circuit base material and covers the area where the power divider network is located. The cavity dielectric sliding type phase shifter can better improve main performance indexes and reduce production cost.

Description

technical field [0001] The invention relates to the technical field of base station antennas, in particular to a cavity medium sliding phase shifter and a base station antenna. Background technique [0002] With the development of mobile communication, the performance requirements of the base station antenna are getting higher and higher. In the base station antenna system, the cavity dielectric sliding phase shifter changes the phase of the feeding of the radiation unit in the base station antenna, and realizes the radiation beam. Forming and scanning; the performance of the cavity dielectric sliding phase shifter directly determines the performance quality of the base station antenna, which in turn affects the quality of the entire network coverage. [0003] The main performance indicators of the cavity dielectric sliding phase shifter are: bandwidth, standing wave, port amplitude and phase linearity, and phase shift range. The bandwidth is the frequency band range in whi...
