Embodiments of the present invention provide a dielectric resonator, a dielectric filter using the dielectric resonator, a transceiver, and a base station, relate to the technical field of communications device components, and solve a problem that a loss indicator of an existing dielectric filter cannot meet a filtering requirement of a base station. The dielectric resonator includes a body made of a solid-state dielectric material, where a dent is disposed on a surface of the body, and the surface of the body and a surface of the dent are covered with a conducting layer; the dielectric filter includes at least two of the foregoing dielectric resonators. Another type of dielectric filter includes a body made of a solid-state dielectric material, where at least two dents are disposed on a surface of the body, a hole and/or a groove is disposed between adjacent dents on the body, and the surface of the body is covered with a conducting layer. The transceiver includes the foregoing dielectric filter. The base station includes the foregoing transceiver. |
