Abstract :
In this study, four H-field probes having different feeding structures, including a strip line, a microstrip line, a coplanar waveguide (CPW), and a conductor-backed CPW (CB-CPW), were investigated and compared. The sensitivity, calibration factor, E-field isolation, and spatial resolution of the magnetic probes were calculated and evaluated. It was found that all these probes can be used to measure the near-field radiation from and the RF current in an IC pin or a trace on a printed-circuit board (PCB).
