Abstract
The invention discloses a phase shifter dielectric plate, which is arranged between a phase shift circuit and a cavity and moves along a preset locus, wherein the dielectric plate is provided with a plurality of protrusions for pressing against the top wall or the bottom wall of the cavity, and the protrusions are higher than the plane of the dielectric plate. When the phase shifter dielectric plate is applied to a phase shifter, the dielectric plate is in tight fit with the cavity, and the problem of high signal index fluctuation in the moving process of the dielectric plate due to a large clearance between the dielectric plate and the cavity is solved; moreover, because the contact area between the protrusions and the cavity is small, high friction is not produced between the both, and abnormal transmission of the dielectric plate is avoided. In addition, the invention further discloses a phase shifter adopting the dielectric plate.
