Resonance suppressed magnetic probe for measuring electromagnetic field intensity

A rectangular magnetic field probe incorporating bonding wire is proposed, and its calculated and measured characteristics are presented. The proposed probe effectively suppresses the emission of electromagnetic fields from the edge of the ground plane, and as a result the scanning range of the probe is enhanced as compared with that of the conventional ones. With the probe tangential magnetic fields over the microstrip line are measured and compared with the field intensity measured with the conventional probe.
