Farfield region
WebThe field, which is far from the antenna, is called as far-field. It is also called as radiation field, as the radiation effect is high in this area. Many of the antenna parameters along … WebFar Field or Fraunhofer Region. The far field region is the most important, as this determines the antenna's radiation pattern. Since antennas are used to communicate wirelessly from long distances, this is the region of …

Although the far field is the usual region of antenna function, certain devices that are called antennas but are specialized for near-field communication do exist. Magnetic induction as seen in a transformer can be seen as a very simple example of this type of near-field electromagnetic interaction. See more The near field and far field are regions of the electromagnetic (EM) field around an object, such as a transmitting antenna, or the result of radiation scattering off an object. Non-radiative near-field behaviors dominate close to … See more The separation of the electric and magnetic fields into components is mathematical, rather than clearly physical, and is based on the … See more The near field itself is further divided into the reactive near field and the radiative near field. The reactive and radiative near-field designations are also a function of wavelength (or … See more Local effects • Fraunhofer diffraction for more on the far field • Fresnel diffraction for more on the near field See more In a normally-operating antenna, positive and negative charges have no way of leaving the metal surface, and are separated from each other by the excitation "signal" voltage (a transmitter or other EM exciting potential). This generates an … See more Solving Maxwell's equations for the electric and magnetic fields for a localized oscillating source, such as an antenna, surrounded by a homogeneous material (typically vacuum or air), yields fields that, far away, decay in proportion to $${\displaystyle 1/r}$$ where … See more 1. ^ Amplitude fall-off is not to be confused with the power fall-off; power falls off as the amplitude squared.
