ABSTRACT:
A dielectric resonator designed so that there is substantially no loss in a conductor on the surface of a casing forming a shielded cavity, and so that the unloaded Q and the resonant frequency can be changed independently of each other. A cylindrical dielectric block having a pair of electrodes formed respectively on its two opposite surfaces is disposed in a metallic shielded-cavity casing so that one of the electrodes is in contact with an inner bottom surface of the shielded-cavity casing. This electrode is electrically connected to the shielded-cavity casing by soldering or the like. Input/output connectors are coupled to the other electrode on the cylindrical dielectric block.
