Abstract
A multimode dielectric resonator device is provided in which a dielectric core can be easily disposed in a cavity, a dielectric resonator device comprising resonators in plural stages can be obtained, and the Q is maintained at a high value. Dielectric cores to resonate in plural modes such as TM &dgr;−(x−z), TE &dgr;−y, TM &dgr;−(x+z) or the like are supported substantially in the center of a cavity by means of a support in the state that the cores are substantially separated from the inner walls of the cavity at a predetermined interval, respectively.
