Abstract
In this paper, a model describing frequency dependentcharacteristics of a sandwiched microsrtrip with aferromagnetic core, is developed. The approach is basedon the assumption, that the characteristics of a sandwichedmicrostrip are mostly determined by a quasi-TEM mode. Frequency profiles of the inductance and resistance perunit length, attenuation, and wave-length are calculated.The increase of the inductance per unit length and thewavelength shortening are obtained due to the presence ofa Ni Fe ferromagnetic core. The results of modeling arediscussed and compared with experiments
