Abstract Ferromagnetic microwires are widely applied in the ultrahigh frequency engineering. In this work, a system on the basis of a ZVA-67 vector network analyzer which makes it possible to measure the parameters of ferromagnetic resonance of microwires in a frequency range from 0.1 to 14 GHz is proposed. The impedance of FeCoNi/CuBe and CoFeSiB microwires is approximated using the values of the components of the main diagonal of the magnetic susceptibility tensor. The proposed method makes it possible to find interesting characteristic features of the electromagnetic properties of microwires in the regions of frequencies and magnetic fields where ferromagnetic resonance is observed.
