VSWR to Reflection conversion calculator

VSWR to Reflection Formula

Γ = (VSWR – 1) / (VSWR + 1)

Formula Explanation

The VSWR to Reflection conversion calculator uses this formula to determine the reflection coefficient (Γ), which indicates how much of a signal is reflected due to impedance mismatch in a transmission line. A perfect match results in Γ = 0, meaning no reflected power, while a higher VSWR produces a larger reflection coefficient.

Uses of VSWR to Reflection conversion calculator

  • Used in RF and microwave engineering to measure signal reflections.
  • Helps in designing antennas and transmission lines for maximum efficiency.
  • Assists engineers in assessing impedance matching in communication systems.
  • Essential for tuning circuits to minimize power loss and signal degradation.

Formula Example

Suppose the measured VSWR is 2.5.

Using the formula: Γ = (2.5 – 1) / (2.5 + 1) = 1.5 / 3.5 = 0.4286

The reflection coefficient is 0.4286, indicating that approximately 42.86% of the signal amplitude is reflected due to mismatch.
