PURPOSE:To provide the dielectric resonator and its manufacture in which the strength of coupling between the resonators and the resonance frequency of the resonator of each stage are easily changed. CONSTITUTION:An inner conductor is partially cut in the axial direction at a position opposite to an adjacent air gap or at a position close to an outer conductor 6 at an open end part of the inner conductor in air gaps 2a-2d. The resonance frequency of the resonator of each stage is set or adjusted and the strength of coupling between the resonators is set or adjusted to a desired strength, and the resonance frequency of the resonator is set or adjusted independently of the strength of coupling between the resonators, Since the strength of coupling between the resonators is adjusted increasingly or decreasingly and the strength of the coupling between the resonators is comparatively largely changed, a desired characteristic is easily obtained. |
