Embodiments of the present invention relate to the technical field of communications device components, and provide a dielectric resonator and a dielectric filter, a transceiver and a base station using the same, which solve the problem that a loss indicator of existing dielectric resonators cannot meet filtering requirements of a base station. The dielectric resonator comprises a body made of a solid dielectric material, wherein a recess is arranged on the surface of the body, and the surface of the body and the surface of the recess are covered by a conductive layer. A dielectric filter comprises at least two of the dielectric resonators. Another dielectric filter comprises a body made of a solid dielectric material, wherein at least two recesses are arranged on the surface of the body, a hole and/or groove is arranged between two adjacent recesses, and the surface of the body is covered by a conductive layer. The transceiver comprises the dielectric filter. The base station comprises the transceiver. |
