Voltage Standing Wave Ratio (VSWR) Formula

LaTeX Go

Voltage Standing Wave Ratio = (1+Reflection Coefficient)/(1-Reflection Coefficient)
VSWR = (1+Γ)/(1-Γ)

How are VSWR and reflection coefficient related?

A wave is partly reflected when a transmission line is terminated with an impedance unequal to its characteristic impedance. Reflection coefficient is a complex number that describes both the magnitude and the phase shift of the reflection and it directly corresponds to VSWR.

How to Calculate Voltage Standing Wave Ratio (VSWR)?

Voltage Standing Wave Ratio (VSWR) calculator uses Voltage Standing Wave Ratio = (1+Reflection Coefficient)/(1-Reflection Coefficient) to calculate the Voltage Standing Wave Ratio, The Voltage Standing Wave Ratio (VSWR) formula is defined as the ratio of maximum to minimum magnitudes of voltage or current on a line having standing waves and can be represented with respect to Reflection Coefficient. VSWR terms of reflection coefficient, is a measure of impedance matching of loads to the characteristic impedance of a transmission line. Voltage Standing Wave Ratio is denoted by VSWR symbol.

How to calculate Voltage Standing Wave Ratio (VSWR) using this online calculator? To use this online calculator for Voltage Standing Wave Ratio (VSWR), enter Reflection Coefficient (Γ) and hit the calculate button. Here is how the Voltage Standing Wave Ratio (VSWR) calculation can be explained with given input values -> 3.347826 = (1+0.54)/(1-0.54).
