An improvd dielectric ceramic composition for high frequencies and a method for preparation of the same, capable of being advantageously used for a substrate of dielectric resonator, glabal positioning system and the like in high frequency regions, which consists of a main component of Zr1-XSnXTi1+YO4 and sintering aid component of MnO2, NiO and Sb2O3, wherein the molar ratio X and Y are respectively, 0.1</=X</=0.3 and -0.1</=Y</=0.1 and the sintering aid component essentially consists of, based on the total amount of the main component, 3% or less of MnO2 and 2 wt % or less of NiO and Sb2O3 in a combined amount.
