摘要： In a dielectric filter, from the top surface to the bottom surface of a substantially rectangular dielectric block, inner-conductor holes are formed. On the inner surfaces of the inner-conductor holes, inner conductors are formed except where non-conductor portions are formed in proximity to one of the top and bottom surfaces, in which the apertures of the inner-conductor holes are formed. On the outer surface of the dielectric block, an outer conductor is formed substantially over the entire outer surface, and input and output electrodes isolated from the outer conductor are coupled with the non-conductor portions in the respective inner-conductor holes at the ends of the dielectric block in the direction of array of the inner-conductor holes. In one of the surfaces in which the apertures of the inner-conductor holes are formed, or in one of the surfaces at the ends of the dielectric block in the direction of array of the inner-conductor holes, a concavity is formed, the inner surface thereof being covered with the outer conductor.

摘要： The present invention provides a dielectric resonator, a dielectric filter, a dielectric duplexer capable of reducing leakage of electromagnetic waves and capable of being miniaturized, and a communication apparatus incorporating the same. In each of the dielectric resonator and filter, inside a dielectric block, there is formed a L-shaped inner-conductor-formed hole having a bend at some point of the hole in a manner extending from an outer surface of the dielectric block to a surface perpendicular to the outer surface. An inner conductor is formed on the inner surface of the inner-conductor-formed hole. On the substantially entire outer surfaces of the dielectric block, there is disposed an outer conductor, with one end of the inner-conductor-formed hole open-circuited and the remaining end of the hole short-circuited. Around the edge of the open-circuited end there is formed an outer coupling electrode. This structure enables formation of the dielectric resonator and the dielectric filter having the L-shaped inner-conductor-formed holes.

摘要： A small-sized low-loss dielectric resonator, dielectric filter, and dielectric duplexer, and a communication device using such an element. Through-holes are formed in a dielectric block. The inner surface of each through-hole is covered with a thin-film multilayer electrode consisting of an outermost conductive layer and a multilayer region including thin-film conductive layers and thin-film dielectric layers. An outer conductor having a similar thin-film multilayer electrode structure is formed on the outer surface of the dielectric block. An outer conductor in the form of a single-layer electrode is formed on a short-circuited end face of the dielectric block thereby connecting together the thin-film conductive layers of the inner and outer conductors.
