Dielectric Resonator and Dielectric Filter

A dielectric filter, comprising a body part, a cover, and a first dielectric resonator;

• wherein the body part comprises a first port and a second port, and the first port and the second port are configured to input and output signals;
• wherein a first cavity is further formed in the body part, and a first support kit is disposed at a bottom of the first cavity;
• wherein the first dielectric resonator is contained in the first cavity and is disposed on the first support kit;
• wherein the first dielectric resonator comprises a dielectric body, wherein at least two holes are disposed on the dielectric body and the dielectric body comprises a top plane and a bottom plane, wherein the at least two holes penetrate through the top plane and the bottom plane of the dielectric body;
• wherein the dielectric body has a first mirror plane and a second mirror plane, and the second mirror plane and the first mirror plane are perpendicular to each other and both penetrate through the top plane and the bottom plane of the dielectric body;
• and
• wherein the at least two holes are not mirror symmetric relative to the first mirror plane and the second mirror plane.
