Calculation Formula

Far-Field Distance (R) = 2 * (Diameter^2 / Wavelength)

Where:
R = Far-Field Distance (m)
D = Antenna Diameter (m)
λ = Wavelength (m)

Result

How to Use the Far Field Calculator

  1. Enter the frequency of the antenna in MHz.
  2. Enter the wavelength of the antenna in meters.
  3. Enter the diameter of the antenna in meters.
  4. Click the "Calculate" button to compute the far-field distance.
  5. The result will be displayed in meters.

Working Principle

The far-field region is a region where the wavefronts are approximately planar. It is typically defined as the region where the angle between the direction of propagation and the radial distance from the source is less than 30 degrees. The far-field distance can be calculated using the formula:

R = 2 * (D^2 / λ)

where R is the far-field distance, D is the diameter of the antenna, and λ is the wavelength.
