    Abstract: A dielectric filter includes resonator electrodes, an inter-stage coupling capacitor electrode, and an input/output coupling capacitor electrode on dielectric substrates, respectively. The resonator electrodes are electro-magnetically coupled to each other to form a tri-plate structure, are made of a metallic foil embedded in a resonator dielectric substrate. Another dielectric filter includes an upper shield electrode dielectric substrate, an inter-stage coupling capacitor dielectric substrate, a resonator dielectric substrate, and an input/output coupling capacitor dielectric substrate which are made of a composite dielectric material including a high-dielectric-constant material and a low-dielectric-constant material. The above described arrangement provides the dielectric filter with an improved Q factor of a resonator, a low loss, and a high attenuation.

    Abstract: The structure manufacturing method calculates an equivalent material constant of a structure constituted by a plurality of materials, for example for deriving the thermal conductivity of a printed circuit board, and includes a shape data input portion 3 that inputs shape data, material data input portion 4 that inputs material constant data, a dividing portion 5 that divides the structure into a plurality of small regions, and a small region interior calculation portion 6 that calculates equivalent material constants in the small regions. The method also includes a spectrum calculation step of obtaining a frequency spectrum in each minimum region of the small regions by performing a Fourier transformation of the distribution of the equivalent material constant.

    Abstract: A small multilayer filter, in which a phase shifter may be constituted without increasing overall size of the filter. The overall size may be reduced without deteriorating the characteristics. Above the open end of a plurality of strip lines 4A provided on a dielectric layer 4, a coupling sector 3A of input/output pattern is placed to face it with a dielectric layer 3 interposed. An inductance L1, L2 is formed by connecting a side electrode 7A, 7B with a continuity sector 3B of input/output pattern; and said side electrode 7A, 7B with an input electrode 8A, output electrode 8B, respectively, by means of an electrode pattern 5A.
