CERAMIC PACKAGE

摘要

A ceramic package is formed of a ceramic, so that if the complex specific dielectric constant is represented by epsilon r = epsilon r'- j epsilon r", and the complex specific permeability is represented by mu r = mu r' - j mu r", wherein j = 2ROOT -1, a portion of the whole of the ceramic portion of the ceramic package satisfies the following relations: epsilon r' > 20, epsilon r" > 0, mu r' > 1, and mu r" > 0. ex
