The finite element method (FEM) analysis on the effects of soft magnetic film as a noise suppressor at GHz range was discussed. It was found that the coplanar transmission line was with the total width of 400 μm and 50 μm width of signal line, 3 μm thickness respectively. The analysis showed that the change of the magnetic field distribution, the induced surface current density on the coplanar transmission line and hence the rf noise suppresson by magnetic films were significant as a function of the magnetic film width/slit width and magnetic film thickness.
