ABSTRACT:
A dielectric resonator apparatus is provided with a dielectric resonator which has a generally spherical dielectric placed within a shield case having a rectangular cavity, and uses each resonance of a x mode, a y mode and a z mode of TE.sub.101, where an electric field is caused respectively around a x axis, a y axis and a z axis of a rectangular coordinate system predetermined in the dielectric, and an external coupling means for coupling the above described resonator to an external circuit, whereby the dielectric resonator apparatus, which has no-load Q larger than in the conventional embodiment, can be made smaller in size, and also, can realize three resonators with one apparatus.
