Claims

[Scope of utility model registration request]

A coaxial dielectric resonator in which a dielectric material is filled between the inner and outer conductors is provided with a portion where the conductor is cut out on the short-circuit side of the outer conductor at one end perpendicular to the axis of the resonator. A frequency-variable coaxial dielectric resonator characterized in that the tuning frequency of the resonator is adjusted by changing the area covered by a metal plate that rotates around the center.
