Hi everyone,
I've measured the transmission of a glass material at microwave frequency range, using two horn antennas, and absorbers(RAM) to limit reflections. The S21(dB) received using the VNA gave me unconvincing results( not really sure though). There was insignificant change in magnitude between S21(air) dB and S21(glass) dB. However there was significant difference of around 11deg in phase between S21(air) deg and S21(glass) deg. Can any experienced person say whether the readings I got are ok or not?
Many Thanks
