Abstract

The invention provides an antenna, a base station and a phase shifting device. The phase shifting device comprises a fixed medium seat and a movable medium seat, the pivoting end of the movable medium seat is pivotally arranged on the fixed medium seat, and the fixed medium seat forms an arc-shaped groove half surrounding the free end on the rotation motion path of the free end of the movable medium seat; a fixed transmission line is arranged on at least one surface of the arc-shaped groove of the fixed medium seat, and signal output ports are respectively formed at two ends of the fixed transmission line; at least one surface of the movable medium seat is provided with a movable transmission line, and the movable transmission line is electrically conducted with the signal input port on the fixed medium seat; and the fixed transmission line is electrically coupled with the movable transmission line. According to the phase shifter, the problems that when a traditional phase shifter is applied to a Massive MIMO antenna, installation is complex, and parts are numerous are solved, and the assembly and production difficulty of the whole antenna is lowered.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and in particular relates to a phase shifting device, an antenna configured with the phase shifting device, and a base station configured with the antenna. Background technique [0002] With the continuous development of mobile communication technology, users have higher requirements for transmission delay, transmission rate, stability and system capacity of phase-shift communication, and the fifth-generation mobile communication network has emerged as the times require. At present, the 5G communication network under continuous construction has gradually matured and been put into commercial use. As the main carrier of signal transmission and reception in communication, the antenna of mobile communication base station, its performance directly affects the overall performance of the communication network and the user's perception experience. In the mobile communication network It plays...
