Contactless vector network analysis using diversity calibration with capacitive and inductive coupled probes

[摘要] Contactless vector network analysis based on a diversity calibration isinvestigated for the measurement of embedded devices in planar circuits.Conventional contactless measurement systems based on two probes for eachmeasurement port have the disadvantage that the signal-to-noise systemdynamics strongly depends on the distance between the contactless probes.

In order to avoid a decrease in system dynamics a diversity based measurementsystem is presented. The measurement setup uses one inductive and twocapacitive probes. As an inductive probe a half magnetic loop in combinationwith a broadband balun is introduced. In order to eliminate systematic errorsfrom the measurement results a diversity calibration algorithm is presented.Simulation and measurement results for a one-port configuration are shown.
