Micron size U-type barium hexaferrite powder have been synthesized by solid state reaction process. Powder X-ray diffractometer technique has been used to confirm the phase of hexagonal through the calculate lattice parameters. Field emission scanning electron microscope was used to morphology of synthesized powder and prepared composites. Complex permittivity, complex permeability and absorbing properties have been studied for all polymeric composites by using the Agilent vector network analyzer in the frequency range of 2-18 GHz. The minimum RL was observed as -32.38dB for the absorber with thickness of 3.6mm.
