Abstract

Embodiments of the present invention provide a phase shifter and an antenna, and relate to the technical field of communications. The phase shifter includes: a cavity, a fixed assembly located in the cavity, a sliding assembly, a control rod for controlling the sliding of the sliding assembly, and a medium part; the fixed assembly is provided with a first belt line group, the first belt line group It includes two belt lines; the sliding assembly is located above the fixed assembly, and a second belt line group is arranged in the sliding assembly; the second belt line group includes two belt lines, and the two belt lines in the second belt line group are connected with the first The two striplines in the stripline group are respectively coupled and electrically connected; wherein, each stripline in the first stripline group and / or the second stripline group includes a first stripline part and a second stripline part, the first The width of the strip line part is greater than the width of the second strip line part, and the dielectric part is arranged on the peripheral side of the second strip line part, and the difference between the impedance formed by the dielectric part and the second strip line part and the impedance of the first strip line part in the first range. The effect of reducing the volume of the phase shifter is achieved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a phase shifter and an antenna. Background technique [0002] A phase shifter is a device that can adjust the phase of a wave, and it is the core component of an antenna. The phase shifter changes the pattern of the antenna by changing the phase of the signal reaching the antenna, thereby achieving the purpose of remote control of the network coverage area. [0003] The existing phase shifter generally includes a fixed printed circuit board (English: Printed Circuit Board, PCB for short) and a sliding metal. Wherein, a fixed circuit is arranged in the fixed PCB, and the sliding metal is U-shaped. When the sliding metal and the fixed circuit slide relative to each other, the phase of the current passing through the fixed circuit will change. [0004] In the process of realizing the present invention, the inventor found that the prior art has at least the following problem...
