摘要： This dielectric resonator comprises a cylindrical hollow case made of metal, a cylindrical hollow dielectric resonator element which is fixed and held in the case, and a dielectric tuning unit which is inserted into or withdrawn from a hollow portion of the dielectric resonator element. The hollow portion of the dielectric resonator element is formed by at least one, or a plurality of, cutout portions which extend along respective radii of the cylindrical dielectric resonator. In this dielectric resonator, the overall effective dielectric constant as a whole can be varied by inserting the tuning unit into or withdrawing it from the hollow portion of the dielectric resonator element. When the tuning unit is withdrawn from the hollow portion of the dielectric resonator element, part of an electric field path at the dielectric resonator element is interrupted by the cutout portions.
