The effect of barium titanate on the dielectric constant of a composite based on an epoxy press material

Abstract The paper considers the effect of the introduction of barium titanate (BaTiO 3 ) on the dielectric properties of a composite material based on an epoxy press material. The technology for preparing a composite material with a high dielectric constant is presented. The physicomechanical and dielectric properties of the composite are presented. The possibility of increasing the dielectric constant of the material is shown, as well as the technology of manufacturing the housing elements of spiral antennas. It was found that filling with 30 % of the BaTiO 3 mass increases the dielectric constant by 1.5 times.
