Hi all,

I did a free space measurement (Transmission) between 5 and 6 GHz. I get the Phase from VNA (Figure) . It seems to me that the Group time is negative (the Slope of the unwrapped phase is positive). Is something wrong with this measurement ? I repeated the calibration and measurement, i got the same result!

Thank you
