Abstract
Abstract The paper describes the fabrication of new artificial material through a compression-molding technique. Four composites PVDF/BaFe11·7Al0·3O19 (HF) were produced at various PVDF concentrations (5%, 10%, 15%, and 20%), wt.%. The produced samples were examined by an X-Ray diffraction (XRD) analysis and Fourier transform infrared (FTIR) spectroscopy. The examination proved that the produced samples formed the required hexaferrite and its composites. The magnetic and electrical characteristics of all the samples were examined by using a vibrating sample magnetometer (VSM) and a vector network analyzer. The samples were tested for electromagnetic shielding and Antenna application at a frequency of 2.45 GHz. The study of the dielectric properties suggests that 10% PVDF is the optimized ratio composite, which can provide a perfect opportunity for improving the Antenna gain and efficiency. The shielding efficiency due to the reflection of 10% PVDF composite is 32 dB. Therefore, PVDF/HF composites can be promising candidates for practical applications such as high frequency, electromagnetic interference (EMI) suppressor, electronic, communication, and future gigahertz antenna applications.
