This converter transforms a reflection coefficient (Γ) into VSWR (Voltage Standing Wave Ratio), thus making it possible to evaluate the quality of the adaptation of a transmission line or an antenna. The tool helps engineers quantify apparent impedance and identify mismatches in RF systems.
Formula
VSWR = (1 + |Γ|) / (1 – |Γ|)
Explanation of the formula
The reflection coefficient Γ measures the proportion of signal reflected by a mismatched impedance. The VSWR formula uses the absolute value of Γ to calculate the ratio of the maximum peak to the minimum peak of the voltage in the transmission line. The closer the VSWR is to 1, the better the impedance matching.
Uses
- Evaluate the quality of antenna or transmission line matching.
- Identify mismatch points in RF and microwave systems.
- Optimize circuit and filter design to reduce reflection.
- Monitor the performance of transmission systems and ensure energy efficiency.
