- In the context of antennas, the far-field distance is the distance from the antenna at which the electromagnetic radiation pattern becomes essentially stable12345. Key points about the far-field distance include:
- It is the distance from the transmitting antenna to the beginning of the Fraunhofer region or far-field region.
- In the far-field region, the radiation pattern does not change shape as the distance increases.
- The behavior of the radiated waves can be approximated as a spherical wavefront, a plane wave, or a well-defined beam.

The radiation pattern does not change shape in the far-field region as the distance increases. The radiation behavior of antennas is characterized by their far-field radiation pattern.www.emc-directory.com/calculators/far-field-distan…The region upto the distance of 2 D 2 /λ from the antenna is referred as near field region. Where, D is the antenna diameter and Lambda is wavelength of free space. The region above the distance of 2 D 2 /λ is referred as far field region.www.rfwireless-world.com/Tutorials/near-field-vs-fa…The far field is the region far from the antenna, as you might suspect. In this region, the radiation pattern does not change shape with distance (R). Although the E- and H- fields still die off as 1/R, the power density dies off as 1/R^2.www.antenna-theory.com/basics/fieldRegions.phpAntennas are usually used to transfer signals at large distances which are considered to be in the far-field region. One condition that must be met when making measurements in the far field region is that the distance from the antenna must be much greater than the size of the antenna and the wavelength.www.everythingrf.com/community/what-are-near-fi… - People also ask
