| '''Antenna array''' is a systematic arrangement of ]s working together. | |||
| Kinds of antenna array include: | |||
| *], a geometrical arrangement of antenna elements with a deliberate relationship between their currents, forming a single antenna usually to achieve a desired radiation pattern | |||
| *], used to define an antenna array | |||
| *], An antenna array where the phase shifts (and amplitudes) applied to the elements are modified electronically, typically in order to steer the antenna system's directional pattern, without the use of moving parts | |||
| *], a phased array in which a signal processor computes phase shifts to optimize reception and/or transmission to a receiver on the fly, such as is performed by cellular telephone towers | |||
| *] of radio telescopes or optical telescopes, used to achieve high resolution through interferometric correlation | |||
| *], using the Watson-Watt technique whereby two Adcock antenna pairs are used to perform an amplitude comparison on the incoming signal | |||
