Abstract
In a high frequency circuit property measurement method, prior to property measurements of a high frequency circuit with RF measurement probe heads, RF measurement probe heads are calibrated using a calibration pattern comprising a signal line having a characteristic impedance and extending on a dielectric substrate, a first GND pad having one end disposed close to and at an interval from a first end of the signal line, a second GND pad having one end disposed close to and at an interval from a second end of the signal line, and a conductor electrically coupling the first GND pad to the second GND pad.
