Converter from VSWR to Reflection Coefficient

This converter allows you to transform the line standing wave ratio (VSWR) into a reflection coefficient (Γ) . It helps to understand the degree of matching of a transmission line or antenna and to evaluate losses due to reflections in an RF system.

Formula

Γ = (VSWR – 1) / (VSWR + 1)

Explanation of the formula

The formula expresses the reflection coefficient Γ as the proportion of reflected wave compared to the incident wave. If the VSWR is 1, this indicates perfect matching and Γ = 0. For VSWR greater than 1, the Γ coefficient increases and shows the percentage of energy reflected by the loading element or antenna.

Uses

  • Evaluate the suitability of a transmission line or antenna.
  • Determine the amount of power reflected in an RF system.
  • Assist in the design and optimization of antennas and matching circuits.
  • Provide actionable data for performance analysis of RF networks and devices.
