Near-field measurement system with 3D magnetic-field probe design for dosimetric applications

In this paper the design of a new 3D magnetic field (H-field) probe with a near-field scanning system is presented. The proposed system was developed in order to determine the magnetic near-field emitted by electronic devices. The designed isotropic H-field probe consists of three orthogonal and identical loops each of diameter of 6 mm having 3 turns. The antenna factor of the designed probe is presented for a frequency range from 1 MHz to 1 GHz. In order to verify the performance of the designed probe, magnetic near-field measurements were done for a standard circuit. The comparison between the measured results and the theoretical calculations was performed for validation.
