Abstract
A dielectric resonator device includes a casing for defining a chamber in which a dielectric resonator and a piezoelectric frequency adjusting unit are provided. A portion of the piezoelectric frequency adjusting unit is located adjacent the dielectric resonator. By the voltage applied to the piezoelectric frequency adjusting unit, the piezoelectric frequency adjusting unit changes its shape thereby changing the distance between the portion of the piezoelectric frequency adjusting unit and the dielectric resonator. Thus, the resonance frequency of the dielectric device can be controlled.
