Just one more example. In this case the DUT=5.21[ohm]+325.96[nH].
If you put the V1 and V2 waveforms into the Python program, you will get:
that Z(DUT)=5.21+j14.39[ohm], where X(DUT)=2.0*3.1416*7026kHz*325.96nH=14.39[ohm].
Please also see the Figure 4 of my article, Antenna Impedance, in which case it is concluded that Z(DUT)=5.21+j14.39 [ohm] from the actual measurement.
