Abstract

Magnetic strips aimed at high-frequency carrier-type magnetic field sensors were studied by using various strip widths in a carrier frequency range of gigahertz to obtain conditions for large impedance change. The impedance change was attributed to a magnetic resonance effect. It was shown that dc magnetic field regions at which the maximum change of impedance occur for wide strip elements were closely related to the applied carrier frequencies as expected theoretically. The dc magnetic field for the maximum sensitivity decreased as strips become narrow.
