Etymology

Adjective

omnidirectional (not comparable)

In every direction, especially of a radio system capable of transmitting or receiving signals in all directions, or of a microphone capable of detecting sound from all directions.

(physics, electrical engineering) Having a ring-shaped radiation pattern, with equal radiation in all azimuthal directions.

Usage notes

Because true omnidirectionality is impossible for individual antennas, omnidirectional is generally used in electrical engineering contexts to refer to antennas that can receive signals in all directions in the azimuthal plane. In these contexts, a hypothetical antenna that radiates in all directions equally is called isotropic.

Antonyms

• unidirectional

Coffee Trivia

Coffee has initially been a food – chewed, not sipped. Early African tribes consume coffee by grinding the berries together, adding some animal fat, and rolling the treats into tiny edible energy balls.
