main lobe

Of an antenna radiation pattern, the lobe containing the maximum power (exhibiting the greatest field strength). Note: The horizontal radiation pattern, i.e., 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, i.e., that which is plotted as a function of elevation from a specified azimuth, is also of interest and may be similarly specified. Synonym main beam.
