摘要

A miniature practical active magnetic field (H-field) probe with 0.5 mm × 0.15 mm loop size is designed for electromagnetic interference analysis inelectronic systems from 150 kHz to 12 GHz. This probe is fabricated in afour-layer printed circuit board using high-performance and low-loss Rogersmaterial (RO4350B). A low noise amplifier with 14 dB-gain is applied toamplify the radio frequency detect signal. The spatial resolution of the proposedprobe is verified under the microstrip with different widths (1.55 and0.24 mm). In addition, the verification results indicate that the proposedsmall loop active shielded H-field probe can obtain the better spatial resolutionof 422 μm with liftoff = 100 μm. Regarding to the sensitivity of theprobe, the proposed probe realizes 16.7 dB μA at 3 GHz with theliftoff = 100 μm. compared with other commercial probes and a referenceprobe, the proposed probe has better spatial resolution at 150 kHz–12 GHzand sensitivity at 1.5–12 GHz.
