Abstract
Disclosed are a dielectric resonator having simple configuration applicable to a multiple mode with no electrical signal transmission loss, and a method of controlling a resonance state (coupling mode) in the dielectric resonator. The dielectric resonator includes a cylindrical or polygonal external conductor, and a dielectric resonant element arranged at the substantially center of the external conductor. A notched portion is formed at a part of the dielectric resonant element so as to control the resonance state of the dielectric resonator.
