Calculation method
Calculation method
Scaled dimensions (m)
Each reference dimension × reference frequency/target frequency; all dimensions scale uniformly.
Linear scale factor
Reference frequency/target frequency; feedpoint and material effects need separate tuning.
Symbols and units

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Reference dimensions-frequency, target frequency. Returns Scaled dimensions; tuning still required. 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. Reference antenna element dimensions (m): minimum 1e-12, maximum 1000000000000.0. Reference frequency (MHz): minimum 1e-12, maximum 1000000000000.0. Target frequency (MHz): minimum 1e-12, maximum 1000000000000.0.
