In this paper, different densities within a ceramic are used to provide a wide, continuous range of cofirable dielectric constants for high frequency applications. Cofiring different ceramic materials together to make a single, unified structure to obtain different dielectric constant combinations is quite difficult due to phase stability issues and shrinkage mismatches. However, using various levels of porosity in order to alter the effective dielectric constant in the same material allows… CONTINUE READING
