ABSTRACT:
A dielectric resonance device includes at least one dielectric resonator having a hollow frame body often called the "cavity" in the art, cross-coupled dielectric pillars in the frame body, and an earth conductor on the outer surface of the frame body. The frame body has a pair of opposed openings at opposite ends thereof. A plurality of conductive plates are provided each of which has a first end coupled to the earth conductor and a second end. Two printed circuit boards acting as front and rear panel plates are attached to cover the openings, respectively. The second ends of the conductive plates are coupled by soldering to metal films of the first and second printed circuit boards while having the conductive plates folded to be in area-contact with and electrically connected to the printed circuit boards so as to tightly hold these boards. The dielectric resonator is held in a casing together with the conductive plates and the first and second printed circuit boards. An input/output connector is fixedly attached to the casing. This connector has a conductive portion being electrically connected to one of the first and second printed circuit boards.
