Far-field radiation pattern
In antenna engineering, the far field is the region beyond approximately 10 wavelengths from the antenna where the spherical wave genereated appears approximately planar, which leads to simplified versions of the radiation equations. A key difference from the near-field region is that power is transmitted in the far-field instead of stored (as it is in the near-field).
