Quick Summary

An antenna array is a radio antenna composed of numerous parallel wires. This arrangement allows it to transmit or receive signals more effectively in specific directions than others. Antenna arrays are crucial components in various electronic systems, including radar, radio, and television, where they direct incoming and outgoing radio waves.12

These arrays are designed to concentrate energy and improve accuracy in determining target locations. By combining multiple individual antenna elements, such as dipoles, in a systematic way, signals can be radiated or received in unison, creating a narrow beam. This configuration is known as a phased-array antenna, which can rapidly change the direction of its beam without mechanical movement.3

More powerful antennas were constructed during the 1920s by combining a number of elements in a systematic array. Metal horn antennas were devised during the subsequent decade following the development of waveguides that could direct the propagation of very high-frequency radio signals.
