In this study, partially substituted U-type ferrite (Ba4MexCo2-xFe36O60, Me: Mn, Ni, Zn, x=0.5 and 1.0) powders weresynthesized by sol–gel method. The powders were analyzed for phase formation, morphology and magnetic properties byXRD, FE-SEM and VSM respectively. The synthesized ferrite powders were pressed into a series of toroidal shaped samples,in which the weight ratio of parafn to powder was 1:5. The complex scattering parameters were measured by using vectornetwork analyzer in the frequency range of 2–18 GHz and were employed in the calculation of refection loss with variousthicknesses. The minimum refection loss was observed in the substituted nickel sample as−24.4 dB (absorption rate 99.6%)with a thickness of 2.5 mm and the bandwidth was achieved 4.8 GHz (from 7.5 to 12.3 GHz) for refection loss≤ −10 dBin the substituted zinc sample.
