摘要： A dielectric ceramic composition has a dielectric constant, K, of at least 200 and a dielectric loss, DF, of 0.0006 or less at 1 MHz. The dielectric ceramic composition may be formed by sintering by firing in air without a controlled atmosphere. The dielectric ceramic composition may have a major component of 92.49 to 97.5 wt. % containing 60.15 to 68.2 wt. % strontium titanate, 11.02 to 23.59 wt. % calcium titanate and 7.11 to 21.32 wt. % barium titanate; and a minor component of 2.50 to 7.51 wt. % containing 1.18 to 3.55 wt. % calcium zirconate, 0.50 to 1.54 wt. % bismuth trioxide, 0.2 to 0.59 wt. % zirconia, 0.02 to 0.07 wt. % manganese dioxide, 0.12 to 0.35 wt. % zinc oxide, 0.12 to 0.35 wt. % lead-free glass frit, 0.24 to 0.71 wt. % kaolin clay and 0.12 to 0.35 wt. % cerium oxide. UHF antennas and monolithic ceramic components may use the dielectric ceramic composition.
