Abstract
This research synthesized two types of materials, namely M-type barium hexaferrite Ba0.6Ca0.4Fe12O19 and Ba0.6Ca0.4Fe12O19/Fe3O4/SiO2 nano composite by using ceramic and mechanical milling method. To characterize obtained powder properties, we employed permagraph and vector network analyser (VNA) measurement. Furthermore, complex permeability (μ) and permittivity (ε) were calculated based on VNA measurement signal in The samples have shown a lowest reflection loss of –40.43 dB at 8.46 GHz and –21.14 dB dB at 12.4 GHz for barium hexaferrite Ba0.6Ca0.4Fe12O19 (0%) and Ba0.6Ca0.4Fe12O19/Fe3O4/SiO2 (20%) nano composite, respectively.
