This study investigates microwave absorption properties of Ba-hexaferrite (BaFe12O19) and titanium dioxide (TiO2) particles coated with conducting polymer (PANI) and BaFe12O19-TiO2 mixture in the frequency range of 8-18 GHz. Samples having different magnetic to dielectric mass ratios and various thicknesses from 1.5 to 4 mm have been prepared to investigate effect of magnetic and dielectric fillers together with influence of conducting polymer layer on microwave absorption properties of BaFe12O19-TiO2 composite. Structural, magnetic, and microwave absorption properties of composites have been investigated using X-ray diffraction, scanning electron microscopy and near field microwave measurements using vector network analyzer. Microwave measurements revealed that composites with PANI coating have much higher absorption values which are independent of an absorber thickness. Among PANI coated absorbers, sample having magnetic to dielectric mass ratio of 2 showed better microwave properties in 8-18 GHz range.
