Far-field radiation

WebThe radiating fields are dominant in this region. The equation for the inner boundary of the region is equation R ≥ 0.62 D 3 / λ and the outer boundary is R < 2 D 2 / λ. This holds true for most antennas. The field distribution depends on the distance from the antenna. Far-field Region: This region is also called Fraunhofer region.

WebA similar definition of the far-field region is the region where the radiation pattern — the locations of local minima and maxima in space — is independent of the distance to the wave source. This is equivalent to the criterion for Fraunhofer diffraction in optics, which occurs for Fresnel numbers, F = a2/λ R, much smaller than 1. fantasy football ppr player rankings
