# Reactive near-field, Radiating near-field, Far-field regions

## Formula

\(Reactive\, Near\, Field \leq 0.62\sqrt{ \frac{D^3 }{\lambda }}\)

\(Radiating\, Near\, Field \leq 2\frac{D^2}{\lambda}\)

\( Far\, Field \geq 2\frac{D^2}{\lambda}\)

\(\nu \) = Frequency |

\(\lambda \) = Wavelength |

\(D\) = Largest Dimension of Antenna |
