Abstract
This paper presents a novel low cost three dimensional near-field scanning system consisting of a near field scanner and a three dimensional magnetic probe which reduces the large scanning time of the existing near field scanning systems and increases the spatial resolution. The paper focuses on the design, calibration and validation of a printed circuit three dimensional magnetic field probe. The proposed probe is printed on both sides an FR4 substrate of 3.2mm height. The total dimensions of the probe are 9×9×3.2mm3. The antenna factor of the designed probes is calculated using TEM cell for a frequency range from 10 MHz to 1 GHz. The proposed scanning system is validated by mapping the magnetic field above a wire over ground structure.
