Applies to antenna far-field calculations using E(V/m). E(V/m) = Electric field strength in volts per meter (V/m) at a distance (d = 1 meter) from an antenna with unity gain (G=1). For other values of d, divide the calculated E(V/m) by 10 for d = 10 m; by 100 for ...
In most cases, the radiation pattern is determined in the far-field region for constant radial distance and frequency. A typical radiation pattern is characterized by a main beam with 3 dB beam-width and side-lobes at different levels (Figure 3). The antenna performance is often described in...

these protruding elements create a large voltage differential between the ends of the antenna and the charged atmosphere during storms even if they are far away. This creates a discharge by the antenna into the atmosphere and
4nec2 is a completely free Nec2, Nec4 and windows based tool for creating, viewing, optimizing and checking 2D and 3D style antenna geometry structures and generate, display and/or compare near/far-field radiation patterns for both the starting and experienced antenna modeler. Can be interface...
The radiation pattern in a far field region remains same with respect to angular position. Near-field obstructions detune the antenna and may kill the antenna radiation. If it is a narrow-band antenna, there are very high chances of objects in its near field disturbing the...
The behavior of an antenna’s electromagnetic waves can be classified into two regions viz. near and far field. Near field (Reactive Region):The distance up to 2*Square (D)/Lambda is called near field region. Here D is the antenna diameter and Lambda is wavelength of free space. This re...
The best case of an antenna placement is far away from electronics or other components like batteries, displays, or large ground planes that harm the effective radiated RF field. As guidelines for the antenna design three antennas of different (but no specific) sizes have been simulated. All ...
Near-field antennas are ideal for use in applications that require a consistent read zone. They can detect tags at a distance but are not always suitable for indoor environments. In addition, near-field antennas can read tags at shorter distances than far-field antennas, which are polarization-...
