Due to high resistivity of the magnetic thin film, no insulating layer is disposed between the CPW line and the film. The insertion loss is very low being less than 0.3 dB and this low value is maintained up to 2 GHz. At a ferromagnetic resonance frequency of 3.3 GHz where a large power loss is observed, the degree of noise attenuation is increased significantly reaching 2dB. This level of noise attenuation is still small for real applications, but, considering a small magnetic volume used in this work, further improvement is expected by simply increasing the magnetic volume and also integrating the magnetic thin film into the CPW transmission line.
