摘要

PROBLEM TO BE SOLVED: To provide a composite dielectric material, a composite dielectric molding superior in antenna gain and appropriate for a lens antenna and a surface mounted antenna or the like, wherein characteristic fluctuations in an individual and between individuals are small.;SOLUTION: This is the composite dielectric material containing a dielectric inorganic filler and organic polymer materials, and the dielectric inorganic filler is composed of high dielectric constant ceramic powders whose dielectric constant is 104 to 180 and low dielectric constant ceramic powders whose dielectric constant is 6 to 18, and which is characterized by that the average particle diameter of the low dielectric constant ceramic powders is 0.27 to 125 times of that of the high dielectric constant ceramic powders.;COPYRIGHT: (C)2004,JPO
