- Main_lobe abstract "In a radio antenna's radiation pattern, the main lobe, or main beam is the lobe containing the maximum power. This is the lobe that exhibits the greatest field strength.The radiation pattern of most antennas shows a pattern of \"lobes\" at various angles, directions where the radiated signal strength reaches a maximum, separated by \"nulls\", angles at which the radiation falls to zero. In a directional antenna in which the objective is to emit the radio waves in one direction, the lobe in that direction is designed to be bigger (have higher field strength) than the others; this is the main lobe. The other lobes are called \"sidelobes\", and usually represent unwanted radiation in undesired directions. The sidelobe in the opposite direction from the main lobe is called the \"backlobe\". The radiation pattern referred to above is usually the horizontal radiation pattern, which is plotted as a function of azimuth about the antenna, although the vertical radiation pattern may also have a main lobe. The beamwidth of the antenna is the width of the main lobe, usually specified by the half power beam width, the angle encompassed between the points on the side of the lobe where the power has fallen to half (-3 dB) of its maximum value.The concepts of main lobe and sidelobes also apply to acoustics and optics, and are used to describe the radiation pattern of optical systems like telescopes, and acoustic transducers like microphones and loudspeakers.".
