Abstract
Multiphase ceramic materials for use in electronic applications such as patch antennas and multilayered ceramic devices may be fabricated by providing a novel combination of a glassy precursor material with operable amounts of a high purity cordierite material. The combined materials are sintered at appropriate temperatures, so that a non-glassy celsian type phase is formed. The materials of the instant invention, fabricated according to the method disclosed herein, demonstrate low dielectric constant (K) and low electrical loss (high Q) characteristics.
