Formula
Γ = (VSWR - 1) / (VSWR + 1), Return Loss = -20 log10(|Γ|)
Notes
Use this calculator as a first estimate. Real RF results depend on antenna placement, ground plane, connectors, cable routing and measurement conditions.
Convert VSWR, return loss and reflection coefficient for RF matching analysis.

No. They are estimates and should be verified with measurements.
PCB layout, cables, connectors, antenna placement and nearby objects affect RF performance.
