Claim:
1. A dielectric resonator, comprising: a sealing cover, a dielectric resonant column, a metal cavity, and an electrically-conductive elastic structure body, the dielectric resonant column located within the metal cavity, wherein: the sealing cover is connected to an upper surface of the dielectric resonant column, and the sealing cover is located at an upper end face of the metal cavity, and the sealing cover is configured to seal the metal cavity; the metal cavity is provided with a groove at an inner bottom surface, and the electrically-conductive elastic structure body is located within the groove at the inner bottom surface of the metal cavity, and the electrically-conductive elastic structure body is configured to support the dielectric resonant column, and the depth of the groove causes a lower surface of the dielectric resonant column to be lower than the inner bottom surface of the metal cavity after the sealing cover seals the metal cavity; and a lower end face of the dielectric resonant column is in contact with the electrically-conductive elastic structure body; wherein the metal cavity is provided with a bulge in the groove at the inner bottom surface; the electrically-conductive elastic structure body has a middle hole, and the middle hole of the electrically-conductive elastic structure body and the bulge in the groove at the inner bottom surface of the metal cavity are matched and connected, so that the relative location of the electrically-conductive elastic structure body to the metal cavity is fixed.
