Abstract
A polymeric composition having a high dielectric constant which varies little with temperature is made from a thermoplastic polymer, a high dielectric ceramic having a dielectric constant of at least about 50 at 1.0 Ghz and 20.degree. C., and a second ceramic material having a dielectric constant of at least about 5.0 at 1.0 GHz and 20.degree. C., where the high dielectric ceramic and the second ceramic material have temperature coefficients that are opposite in sign from one another.
