摘要： 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.

摘要： A dielectric resonator block has at least three resonators and coupling device for coupling the adjacent resonators. A reactance element is added in parallel to the coupling device to provide an attenuation pole. A capacitor block of a dielectric material is provided which has through-holes to form hole electrodes and a surface electrode so that two coupling capacitances are provided. One of the two coupling capacitances serves as the reactance element. One of the hole electrodes of the capacitor block is connected with an external connector, and the other hole electrodes are connected with the resonators.

摘要： A dielectric filter includes a laminate substrate formed by laminating and bonding a plurality of dielectric sheets, belt-like resonance electrodes formed on predetermined bond surfaces of the dielectric sheets, input/output electrodes formed at predetermined positions of an outer periphery of the laminate substrate and connected to the belt-like resonance electrodes, and earth electrodes formed on the outer periphery of the laminate substrate under a non-connection state with the input/output electrodes. The end portions of the belt-like resonance electrodes extend to both side surfaces of the laminate substrate. One end of each belt-like resonance electrode is connected to the earth electrode formed on one of the side surfaces of the laminate substrate and serves as a short-circuit terminal, and the other end of the belt-like electrode is exposed on an ungrounded portion on the opposite side surface and serves as an open terminal.

摘要： 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.
