Abstract
The embodiment of the present disclosure provides a phase shifter, including a cavity, a dielectric phase shifting unit located in the cavity, and a signal transmission line. The dielectric phase shifting unit is located between the cavity shell and a part of the signal transmission line. The dielectric phase shifting unit includes at least one dielectric block with a circular cross-section, and its thickness is gradually changed with the circle center as the center. It uses the rotation of the dielectric block instead of sliding to change the relative dielectric constant of the air strip line, which saves the current extension space required for the sliding of the dielectric block, and obtains a continuously adjustable small-size phase shifter, thereby enabling the miniaturization of the base station.
