Abstract: Doping of various oxides can greatly modify the high-frequency magnetic and dielectric properties and, therefore, significantly influence the impedance matching and bandwidth characteristics of BaCoZnFe $-{16}$O $-{27}$ ferrite/epoxy composites. The experiments show that composites doped with V $-{2}$O $-{5}$ and IrO $-{2}+$V $-{2}$O $-{5}$ are potential candidates for use as EM attenuation materials with low reflectivity and broad bandwidth at S, C, and X microwave bands. The frequency bands for reflectivity $\vert R\vert \leq-10$ dB cover 3.613.7 GHz and 3.011.6 GHz at the thickness of 0.3 and 0.35 cm, and the relative bandwidth $W-{R}=3. 8$ and 3.9 is achieved, respectively, for composites doped with V$-{2}$O $-{5}$ and IrO $-{2}+$V $-{2}$O $-{5}$. © 2006 IEEE.
