main beam
The lobe in the radiation pattern of a directional antenna that includes the region of the maximum radiated power. The center of the main lobe defines the beam axis. The beamwidth in a given plane is usually defined as the angle within which the radiated intensity is at least one-half the intensity in the direction of the beam axis. See antenna pattern.
