PURPOSE:To change continuously the height of a dielectric resonator by the turning of a supporting base by fixing the screwed supporting base to be screwed to a metallic chassis to the end of a spacer. CONSTITUTION:A dielectric resonator 1 is fixed to the supporting base 3 via the spacer 2 and a crew thread screwed to a screw hole of the chassis 4 is screwed to the supporting base 3. The height of the dielectric resonator 1 is changed continuously by turning the supporting base 3. Since the distance (t) between a conductor pattern 6 formed to the dielectric base 5 on the chassis 4 and the dielectric resonator 1 is changed continuously, the coupling between the dielectric resonator 1 and the conductor pattern 6 is changed continuously. |
