Near-field Probe Radiation Profile Boundaries Assessment for Optimal Radiated RF Power Susceptibility Pre-mapping

In this paper, the improved near-field probe power radiation profile investigated. The modelling of the electromagnetic field strength in 80-3000 MHz frequency range in the proximity of the near-field probe was performed. The -6 dB aperture boundaries of the magnetic near-field probe were determined for adaptive scanning height systems in the distance range of 1-15 mm for both X and Z axis. The simulation of improved near-field probe absolute magnetic field strength distribution reference map in open-air conditions is carried out in this work and approximation by 9
