[edit] Summary

Description	Example antenna radiation patterns; the first is the computed pattern for a small pyramidal horn (a directional antenna) with boresight on the +z-axis, the second is the computed pattern for a short dipole aligned with the y-axis. The latter pattern is cut-away to show the circular section on the H-plane (horizontal) cut and the figure-of-8 section on E-plane (vertical) cuts. In each pattern, the distance of the surface from the origin is proportional to the magnitude of the E field at some (large) fixed distance from the antenna in the corresponding direction. I.e. Mod[E] (actually Lim r -> ∞ [Mod[E] r]) is plotted radially as a function of direction.
