Patent ID: 10193205

Abstract:
Embodiments of the present disclosure provide a dielectric resonator, a dielectric filter using the dielectric resonator, a transceiver, and a base station, 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 an indentation is disposed on a surface of the body, and the surface of the body and a surface of the indentation 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 indentations are disposed on a surface of the body, a hole and/or a groove is disposed between adjacent indentations on the body, and the surface of the body is covered with a conducting layer.
