Abstract

The invention relates to the technical field of communications, and discloses a phase shifter and an antenna, wherein the phase shifter includes a phase shifter assembly, a transmission assembly and a drive assembly, the transmission assembly includes a pull rod, a worm shaft and a tablet pressing clamp, and the drive assembly is connected with the pull rod 2. It is used to drive the pull rod to rotate. The worm shaft is fixedly sleeved on the pull rod. The side of the tablet clamp is provided with a tooth segment that matches the worm shaft. Driven by the worm shaft, the sliding vane is driven to move. The phase shifter and the antenna provided by the embodiments of the present invention directly convert the rotation of the drive assembly into the movement of the sliding vane in the phase shifter assembly, reduce the loss of transmission efficiency and accumulated error, and improve the transmission accuracy; The arrangement of components, the overall structure is simple, the assembly operation is convenient, and the size and cost are reduced.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a phase shifter and an antenna. Background technique [0002] With the development of base station antenna technology, antennas are developing towards multi-frequency, compact and efficient, and the requirements for control accuracy and size are becoming more and more strict. As the key component of antenna downtilt adjustment, the phase shifter puts forward higher requirements for its transmission accuracy. [0003] At present, the transmission mode of most phase shifter sliding devices is to first convert the rotation of the motor into the horizontal sliding of the pull rod, and then convert the horizontal sliding of the pull rod into the curved motion of the PCB slider. This structure has the following disadvantages: each rotation There is a loss of transmission efficiency in the transformation of sliding and sliding, and the threads cannot be fully matc...
