Antenna Pattern
Information between two wireless devices is transferred via electromagnetic energy
radiated by one antenna and received by another. The radiated power of most antennas
is not uniform in all directions and has varying intensities. The radiated power in various
directions is called the pattern of the antenna. Each antenna should be mounted so that
its direction of strongest radiation intensity points toward the other antenna or
antennas with which it will exchange signals.
Complete antenna patterns are three-dimensional, although often only a two-
dimensional slice of the pattern is shown when all the antennas of interest are located
in roughly the same horizontal plane, along the ground rather than above or below one
another.
A slice taken in a horizontal plane through the center (or looking down on the pattern) is
called the azimuth pattern. A view from the side reveals a vertical plane slice called the
elevation pattern.
