# Voltage Standing Wave Ratio

Voltage Standing Wave Ratio is a measure of the mismatch between the transmission line and its load, indicating the non-uniformity of the electromagnetic field.

Calculate the Voltage Standing-Wave Ratio (VSWR) using this online calculator. VSWR is a measure of the mismatch between a transmission line and its load, indicating the non-uniformity of an electromagnetic field. Enter the VSWR value to determine the Reflection Coefficient, Reflected Power, Return Loss, and Mismatch Loss. This tool provides insights into the efficiency and signal loss in the transmission line.

|\Gamma| = \frac{{v-1}}{{v+1}}

p = 100 \cdot \Gamma^2

d = 20 \cdot \log(\Gamma)

l = 10 \cdot \log(1 - \Gamma^2)

**Where**:

- v = Voltage Standing Wave Ratio
- Γ = Reflection Coefficient
- p = Reflected Power
- d = Reflected Power(dB)
- l = Mismatch Loss
