Antenna Arrays

Back: Antenna Theory

An antenna array (often called a 'phased array') is a set of 2 or more antennas. The signals from the antennas are combined or processed in order to achieve improved performance over that of a single antenna. The antenna array can be used to:

  • increase the overall gain

  • provide diversity reception

  • cancel out interference from a particular set of directions

  • "steer" the array so that it is most sensitive in a particular direction

  • determine the direction of arrival of the incoming signals

  • to maximize the Signal to Interference Plus Noise Ratio (SINR)
