High Dielectric

Over the past ten years several new ceramic materials have been developed for incorporation in high quality microwave integrated filters. A suitable ceramic dielectric microwave resonator material must have low loss in the microwave region, a low temperature coefficient of dielectric constant, and a high dielectric constant, typically 35-40. Most of the research conducted on the ceramic systems has focused upon phases in the BaO-TiO2 system. Many of the barium polytitanates have dielectric properties suited toward their use in microwave filters. Ba2Ti9O2O and BaTi4O9 are used commercially in the communications industry, and BaTi5O11 may also be a potential candidate for use in these systems.

The carbon fiber/metal oxide/metal oxynitride layer sandwich structure is constructed in the electrode to form a mini-plate capacitor. High dielectric constant metal oxides act as dielectric to increase their capacitance.
