Abstract: A plurality of dielectric sheets are laminated and bonded together to constitute a laminated board. A plurality of strip-shaped resonance electrodes are formed in parallel on a predetermined bonding face of the dielectric sheets, and the strip-shaped resonance electrodes reach opposite edges of the laminated board. Recesses are formed by locally cutting out the portions of the edges of the laminated board in which the respective resonance electrodes are exposed at their particular ends. Grounding electrodes are respectively formed on the obverse and reverse faces of the laminated board, and edge grounding electrodes are formed in the portions of the opposite edges of the laminated board except for the recess.

Abstract: In a laminated dielectric resonator and filter having a folded microstrip line type resonator structure, an internal-to-external grounding conductor distance within which an open-end-side internal conductor pattern is disposed is selected to be shorter than an internal-to-external grounding conductor distance within which a short-circuit-side internal conductor pattern is disposed. In this constitution, since the front end of the resonator structure is loaded with a capacity, the resonance frequency is lowered so that it is possible to provide a resonator having a reduced longitudinal resonator size with respect to the same resonance frequency. In addition, since the resonator has no steps, manufacture and mounting are easy. Accordingly, it is possible to reduce the sizes of the laminated dielectric resonator and filter to a further extent, whereby it is possible to reduce a resonator or filter mounting area in a device.
