Abstract

Dielectric ceramic composition for high-frequency wave is described which has high quality coefficient(Q value) and dielectric constant, and good temperature coefficient of resonance frequency. The dielectric ceramic composition may be represented as following formula: (1-y)CaTiO3-yLa(Mg1/2Ti1/2)O3, where, y is from 0.3 to 0.9.The dielectric composition according to the invention has dielectric constant of 28.6 to 58.6, Qxfo(GHz) of 29,330 to 71,000, and the temperature coefficient of resonance frequency(TCF) ranging from -53.82 to +52.32 ppm/deg. C, which TCF being able to be controlled at a range of +-10ppm/deg. C depending on amount of addition of impurities, so that the ceramic composition may effectively be used in telecommunication system.
