| |Meaning=(''Also called'' aerial; sometimes the more general term [[radiator]] is used.) A conductor or system of conductors for radiating and/or receiving radio [[energy]].
| |
| |Explanation=As used in [[radar]], the antenna is usually "directional," that is, it has the property of radiating or receiving [[radio waves]] in larger proportion in a given direction than in others. It includes both the basic radiating element or [[feed]] (such as [[dipole antenna]] or [[horn antenna]]) and its associated [[reflector]] for focusing the [[energy]]. <br/>''See also'' [[waveguide]], [[loop antenna]], [[beavertail antenna]].
