Abstract

The invention discloses a phase adjusting device and a phase adjusting unit. The phase adjusting device comprises a shielding cavity body, a signal circuit board, a sliding medium and a function lever, wherein the signal circuit board is fixedly arranged in the shielding cavity body, and comprises a base material and a signal band line; the signal band line is arranged on the base material, and comprises a signal transmission line arranged in a first direction; the sliding medium is arranged close to the signal circuit board; the function lever can drive the sliding medium to slide in a second direction; an operation end of the function lever extends out of the shielding cavity body and is the same as the sliding medium in a movement direction; the sliding medium continuously changes an electrical length of the signal transmission line when moving in the second direction. Through the movement of the function lever and the sliding medium in the same direction, the electric length of the signal transmission line is continuously changed, thus the adjustment effect is achieved; the phase adjusting device has the advantages of simple structure and high reliability.

Description

technical field [0001] The invention relates to a communication device, in particular to a phase adjustment device and a phase adjustment unit which can be used for a base station antenna. Background technique [0002] Currently in the field of communication, antennas are widely used in communication devices. The antenna phase shifters in the industry can be divided into integrated and distributed according to the unit arrangement. Among them, Chinese Invention Patent No. 201180001177.8 discloses an integrated phase shifter. The number of phase shifting units is limited by the lateral size, making it difficult to expand, which is not conducive to beamforming of high-gain antennas with many radiating units. [0003] For example, Chinese Invention Patent No. 201410094086.9 discloses a distributed phase shifter, which includes an upper shielding plate, a lower shielding plate, a tie rod, a dielectric block, a conductor strip, and a transmission slide plate. By setting the con...
