CM-Microwave Dielectric Characteristics of Low-Density Spheroplastics Based on Phenylone and Hollow Ceramic Microspheres

The dielectric characteristics of heat-resistant spheroplastics based on hollow ceramic microspheres and a heat-resistant binder based on the aromatic polyamide phenylone were investigated. The dielectric characteristics were measured by the waveguide method on a laboratory bench. The dependences of the dielectric loss tangent on the frequency and the binder content in spheroplastic were obtained.
