Claims

[Claims for Utility Model Registration] A groove is provided on one surface of a dielectric block having a substantially rectangular parallelepiped shape, a through hole is provided that penetrates from the bottom of the groove to the back surface of the dielectric block, and the groove of the dielectric block is External electrodes are placed on the outer peripheral surface other than the forming surface.
An internal electrode is provided on the inner peripheral surface of the through hole, a groove side electrode is provided on a part of the side surface of the groove, and a groove bottom electrode is provided to connect the internal electrode and the groove side electrode. In the dielectric filter, a conductor rod is inserted into the hole with a gap in between, and the externally protruding portion of the conductor rod is used as an external input/output terminal, wherein the conductor rod is rotatably supported within the through hole. and the cross-sectional shape of a part of the conductor rod is made non-axisymmetric so that the distance between the outer peripheral surface of the conductor rod and the groove side electrode changes as the conductor rod rotates. A dielectric filter featuring:
