Abstract: a cubic dielectric block(1) of which five surfaces excluding an upper side are plated with conductor; and a plurality of plated resonators(2,3). The coupling structure consists of: a coupler(4) placed between resonators(2,3), having a hole determined according to the coupling between resonators, and plated with conductor, so that it can adjust the amount of coupling between resonators(2,3); an error correction groove(5) of a depth at the upper side of the coupler(4) inside of which is plated with conductor; and an electrode pattern(6) connecting a side of dielectric block and the error correction groove(5) so that it can be used for grounding.

Abstract: The magnetic composition of dielectric ceramics comprises 70 mol% titania(TiO2), 20mol% barium carbonate(BaCO3), 5-9 mol% neodymium oxide(Nd2O3), 1-5 mol% dysprsium oxide(Dy2O3) and less than 1 mol% copper titanate(CuTiO3). And the compound is sintered at 1,220-1,260 deg.C. The CuTiO3 is prepared by calcinating a mixture of copper oxide and titania having a mole ratio of 1:1. The obtained dielectric ceramics, used for temperature compensation, has a low temperature coefficient, a high permittivity and a low dielectric loss at high frequencies.
