Admitting that it is of interest to examine the phase of the impedance, it is indeed necessary to start from the Touchstone S11 file (.s1p). It is an ASCII file where you find, on each line: the frequency, the real of the S11 then the imaginary of the S11. in the first line there is the standardization impedance (50 Ohms in general)
If you are interested, I have restored the "formulas" allowing you to recalculate the A+jB of the load from S11. It's not trivial even if it's quite simple if we start from the right bases. I do this in Excel.
I don't know how to pass this type of information on the forum.
You could just post a sample excel file.. (of maybe the first 10 lines of a S1P). That's what I've done.
