DIELECTRIC PORCELAIN COMPOSITION FOR HIGH-FREQUENCY WAVE

摘要

PROBLEM TO BE SOLVED: To obtain a dielectric porcelain composition for high-frequency waves excellent in high frequency property with low loss. SOLUTION: This invention relates to a dielectric porcelain composition for high-frequency having high Q value in the microwave and millimeterwave range. The composition is represented by the general formula: ((MgO)1-x (TiO2 )x )1-y (MnO)y (where X is 0.2<=X<=0.55 and Y is 0.002<=Y<=0.01). This porcelain composition has higher Q value compared with the conventional material to which no MnO is added.
