PURPOSE: To facilitate the connection of a conductive plate to a metallic panel for covering the opening surface of a dielectric resonator. CONSTITUTION: One end of the conductive plates 61a, 62a, 71a and 72a is soldered to a conductor 2 provided on the outer surface of the dielectric resonator 5a and the other end of the conductive plates is brought in contact with the metallic panels 8 and 9 and held there between the metallic panels 8 and 9 and cases 13 and 14. Thus, the need of the soldering operation of the conductive plates to the metallic panels 8 and 9 is eliminated, the need of the preheating operation of the metallic panels 8 and 9 and the entire dielectric resonator is eliminated as well and the conductive plates 61a, 62a, 71a and 72a are easily connected to the metallic panels 8 and 9. |
