(electromagnetism)
A part of the radiation pattern of a directional antenna representing an area of stronger radio-signal transmission. Also known as radiation lobe.
(engineering acoustics)

lobe

A curve representing the relative signal strength plotted against the position of the aerial with respect to a target. Side lobes are small lobes of energy radiated by radar aerials in diverging directions to the main beam—usually four, two at an angle of 7° from the main beam and two at angle of 90°. Side lobes may cause false weak echoes. An antenna pattern may have just one lobe, or it may have several lobes. Different lobes may have different magnitudes. The strongest lobe is called the main or major lobe. The weak lobes are called secondary or minor lobes.
