Document Type and Number:
WIPO Patent Application WO/1999/012224
Kind Code:
A1
Abstract:
A dielectric resonance device comprising small resonators in a plurality of stages, and a multi-mode dielectric resonance device having a high Q0 value. A dielectric core of a nearly rectangular parallelopiped shape that resonates in a plurality of modes such as TM01$g(d)-x, -y, -z, and TE01$g(d)-x, -y, -z, is disposed in the central portion of a cavity of a nearly rectangular parallelopiped shape in order to utilize these resonance modes.
