Thermal dependence of “metal-polymer” type composite materials' dielectric properties in ultra-high frequency band

Abstract

A simple relation, which can calculate the temperature dependence of the dielectric permittivity and the dielectric loss tangent of composite metal-polymer is obtained. These materials in the frequency range of 8...12 GHz are investigated. It is shown that the thermal properties of these composites are mainly determined by the properties of the matrix material. The obtained results can be used to predict the temperature dependence of the dielectric parameters of composite metal-polymer with different volume part of the metal phase. Keywords
