PTFE and K‐12 Polymer and Ceramic Composite for RF Propagation

Abstract K‐12 and polytetrafluoroethylene (Teflon) polymer–ceramic composite has been prepared by powder processing method for application of the RF & microwave devices. The fabrication of the polymer and ceramic composite is studied and experimented in this paper. The K‐12 ceramic is used as a filler material and Teflon has been used as a matrix of the composite system. The dielectric properties of the polymer–ceramic composite is in good agreement with the theoretical approaches. The dielectric constant and dielectric loss of the composite is found to be 5 and 0.003, respectively. The dielectric constant of the composite is higher than the individual materials. The relative permittivity and dielectric loss increased with an increase in PTFE content. This will help to miniaturize the RF components and microwave devices for microwave applications.
