Title: Devices using low loss dielectric material

Abstract: Devices are described which utilize a low loss dielectric material. This dielectric material is unique in that it combines low dielectric loss with a high and temperature-stable dielectric constant. The material is made up of BaO and TiO.sub.2 and corresponds closely in composition to the compound Ba.sub.2 Ti.sub.9 O.sub.20. Devices utilizing this material are useful at a variety of frequencies, but are particularly advantageous in the microwave region above 0.5 GHz.
