An Investigation of Electric Field Coupling Effects on High-Frequency Calibration of Near-Field Magnetic Probes

In this paper, the effect of electric field coupling on high-frequency correction results during near-field noise measurements using a magnetic field probe is presented. Due to the increasing influence of electric field coupling in the GHz frequency band, high-frequency distortion of the correction factor of the magnetic field probe occurs, which in turn degrades the final magnetic field correction accuracy of the measurement results. The impact of the electric field coupling on the magnetic field probe and the resulting errors in the correction results were verified through three-dimensional electromagnetic field simulations.
