Reflection Coefficient vs Return Loss vs VSWR
This page describes on Reflection Coefficient vs Return Loss vs VSWR describes difference between Reflection Coefficient, Return Loss and VSWR.
Reflection Coefficient
Reflection Coefficient(RC) = Vreflected/Vincident = (Zl-Z0)/(Zl+Z0)
Transmission Coefficient(TC) = ((2Zl)/(Zl+Z0))
Where, Characteristic Impedance, Z0= Sqrt((R+jWL)/(R+jWC))
Zl is Load Impedance.
Reflection coefficient to Return Loss conversion
Return Loss = -20 Log|RC|
Reflection coefficient to VSWR conversion
VSWR= (1+|RC|)/(1-|RC|)
VSWR to Return Loss conversion
Return Loss(RL) = 20 Log ((VSWR+1)/(VSWR-1))
Return Loss to VSWR conversion
VSWR = (10RL/20+1)/(10RL/20-1)
