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) = V_reflected/V_incident = (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 = (10^RL/20+1)/(10^RL/20-1)
