Summary:
A near-field mapping system has been setup to scan the magnetic field above PCB circuits. A loop-type magnetic probe is used to measure the magnetic field up to 9 GHz. The probe is easily fabricated by printing technology. A set of quasi-periodic notches, which functions as a microstrip filter, is embedded between the feeding port and the sensor to introduce selfresonance suppression characteristics. In order to verify the performance of our new system, EM surface field measurements were conducted for a shorted-microstrip line and an openmicrostrip. The comparison between the measured results and the reference data validate the good performance of our system.
