RF polarization mismatch calculator

Calculate power coupling fraction and polarization mismatch loss with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use power coupling fraction and polarization mismatch loss to compare changes to your inputs. The method and limits below explain the scope.

Power coupling fraction

cos(angle)² for ideal linear polarizations.

Polarization mismatch loss (dB)

−10 log10(coupling); perpendicular ideal polarizations have infinite loss.

Assumptions & limits

Assumptions & limits

  • Relative linear polarization angle. Returns Ideal polarization loss. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification. Relative linear-polarization angle (degrees): minimum -360, maximum 360.
