Mar 21, 2010 #2 V volker_muehlhaus Guest S11 is the input reflection factor: how much of the input signal is actually reflected back to the transmitter. You can convert S11 to the VSWR, which is another parameter to describe antenna matching: **broken link removed**

You can convert S11 to the VSWR, which is another parameter to describe antenna matching: **broken link removed** Click to expand... .... and about VSWR you can read here: **broken link removed** or https://en.wikipedia.org/wiki/Standing_wave_ratio it is about Return loss: https://en.wikipedia.org/wiki/Return_loss in this case you: s11 = RL, it is the same. If you know exactly, what is the s11, try search "Scattering Matrix" or "S-PARAMETERS", for example: **broken link removed** I hope, that I helped you
