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.
