A dielectric resonator capable of changing a resonance frequency (a dielectric resonator)

摘要

The present invention relates to a dielectric resonator which changes the resonance frequency, reduces the occurrence of a mode jump when applied to an oscillator, and can be manufactured at a low cost. A dielectric resonator of the present invention includes: a pair of facing upper and lower conductor plates; A dielectric substrate disposed between the conductive plates; A first electrode formed on one side of the dielectric substrate and having a first opening; A second electrode formed on another surface of the dielectric substrate and having a second opening corresponding to the first opening so that a resonator is formed on a portion of the dielectric substrate disposed between the first opening and the second opening; And a variable capacitance capacitor in which a given magnetic field is located in a portion of the dielectric substrate defined within and around the resonator.
