Abstract

The synthesis of M-type Ba0.5Sr0.5CoxGaxFe12-2xO19 hexagonal ferrite has been performed using conventional ceramic method on which electromagnetic wave absorption in the frequency ranges from 8.2GHz to 12.4 GHz has been observed for the variable composition values. This help us to infer that the refection loss boosts -33.36 dB in the composition x=0.4 at 9.62 GHz at thickness of 2.0 mm. The variations were from -10dB to -20dB in the frequency range of 8.2GHz to 8.704 (B.W 0.5 GHz) & 9.96GHz to 10.97GHz (B.W 1.01GHz) and less than -20dB in the range of 8.78GHz to 9.88GHz (B.W 1.1GHz). Hence the synthesized magnetic ferrite can be used as a substrate for different antennas in X-Band because of the deduced insights in the paper..
