WebJan 21, 2024 · An important approach to the design and optimization of array patterns is the beamforming techniques. Here, the array elements are fed through a network that furnishes the phases and magnitudes … 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.

WebMHz, where does the far-field region begin? The blind application of the r = 2 D2/l formula yields r = 17 cm, which seems incorrect. Reference [3] inserts the caveat that, for the above formula to be valid, D must also be large compared to the wavelength(l), which explains why the second example failed. We next turn to reference [4] (page 30 ...
