In most antennas, the radiation from the different parts of the antenna interferes at some angles; the radiation pattern of the antenna can be considered an interference pattern. This results in zero radiation at certain angles where the radio waves from the different parts arrive out of phase, and local maxima of radiation at other angles where the radio waves arrive in phase. Therefore, the radiation plot of most antennas shows a pattern of maxima called ""lobes"" at various angles, separated by ""nulls"" at which the radiation goes to zero. The larger the antenna is compared to a wavelength, the more lobes there will be.
