In html VSWR (Voltage Standing Wave Ratio)
i find the mistake.
In table:
Table I. VSWR, Reflected Power, and (s11)
You have bad equation for VSWR 5.0 Reflected power should be about -3.02 dB.

How do you get -3.02 dB? I use 20*log10( gamma ) = -3.52 dB. [I did have a typo because previously it said -6 dB for some reason, so thanks for pointing out the anomaly there]
