Antenna Array

Antenna array may refer to:

  • Antenna array (electromagnetic) a group of isotropic radiators such that the currents running through them are of different amplitudes and phases
  • Interferometric array of radio telescopes used in radio astronomy
  • Phased array, also known as a smart antenna, an electronically steerable directional antenna typically used in Radar and in wireless communication systems, in view to achieve beamforming, multiple-input and multiple-output (MIMO) communication or space-time coding
  • Directional array refers to multiple antennas arranged such that the superposition of the electromagnetic waves produce a predictable electromagnetic field.
  • Watson-Watt / Adcock antenna array the Watson-Watt technique uses two Adcock antenna pairs to perform an amplitude comparison on the incoming signal.

Famous quotes containing the word array:

    Any one who knows what the worth of family affection is among the lower classes, and who has seen the array of little portraits stuck over a labourer’s fireplace ... will perhaps feel with me that in counteracting the tendencies, social and industrial, which every day are sapping the healthier family affections, the sixpenny photograph is doing more for the poor than all the philanthropists in the world.
