摘要:
There is provided a dielectric resonator which can suppress a spurious output acting as unnecessary resonance and can prevent the out-of-band characteristics of a filter from being degraded. Electrodes having circular openings are formed on a dielectric substrate, and the dielectric substrate is arranged between upper and lower conductive cases. A resonance region is used as a portion between the openings of the dielectric substrate, and columnar members consisting of a wave absorber are arranged between the upper and lower conductive cases.
