An identifiable segment of an antennaradiation pattern. (Note: A lobe is characterized by a localized maximum bounded by identifiable nulls.)
A pair of channels between a data station and a lobe attaching unit, one channel for sending and one for receiving, as seen from the point of view of the attached data station.
More generally, a lobe may refer to divisions of an organ or other unit, such as the lobes of the lung, the liver or a leaf. A lobule is a small lobe.
In astronomy, the Roche lobe is the region of space around a star in a binary system within which orbiting material is gravitationally bound to that star

The liver is organized into lobules which take the shape of polygonal prisms Each lobule is typically hexagonal in cross section and is centered on a branch of the hepatic vein (called, logically enough, the central vein).
The lobule is typically hexagonal in cross section, with a central vein at its center and portal areas at its peripheral corners.
In cross sections, the lobule is filled by cords of hepatic parenchymal cells, hepatocytes, which radiate from the central vein and are separated by vascular sinusoids.
Laterally, it expands in either hemisphere into a considerable lobule, the superior semilunar lobule (lobulus semilunaris superior; postero-superior lobules), which occupies the posterior third of the upper surface of the hemisphere, and is bounded below by the horizontal sulcus.
In the hemispheres this fissure passes in front of the tonsil, crosses between the flocculus in front and the biventral lobule behind, and joins the anterior end of the horizontal sulcus.
(3) The postpyramidal fissure passes across the vermis between the pyramid and the tuber vermis, and, in the hemispheres, courses behind the tonsil and biventral lobules, and then along the lateral border of the biventral lobule to the postnodular sulcus; in the hemisphere it forms the anterior boundary of the inferior semilunar lobule.
