The main lobe, or main beam, of an antenna radiation pattern is the lobe containing the maximum power. This is the lobe that exhibits the greatest field strength.

[edit] Details

The horizontal radiation pattern, that which is plotted as a function of azimuth about the antenna, is usually specified. The width of the main lobe is usually specified as the angle encompassed between the points where the power has fallen 3 dB below the maximum value. The vertical radiation pattern, that which is plotted as a function of elevation from a specified azimuth, is also of interest and may be similarly specified.
