| Abstract(in English) | To measure magnetic near-field distribution with high spatial resolution, four magnetic near-field shielded loop probes which have deferent coil area are calibrated by comparing with magnetic field strength measured by HP closed-field probe as the standard, on a microstrip line of printed circuit board(PCB). Then, to discuss modes of the emission and the suppression of noise with the conductive plane shielding near the PCB, the magnetic near-field distributions were measured using the calibrated probe. The results on the input impedance of printed line show that the distance between a PCB and a conductivity plane is needed 8 mm to reduce the effect of the electromagnetic coupling. And from the measurement of magnetic field, it was cleared that the changing the area of the conductive plane make the change of magnetic field strength above 300 MHz frequency range. |
