Quick Summary
In electronics, an array refers to a group of elements, such as antennas, arranged to form a complete unit. A common example is a phased-array antenna, which combines many individual dipole antennas. By adjusting the phase of the signals from each element, the direction of the antenna's beam can be rapidly changed without mechanical movement. This technology is crucial for applications like satellite surveillance and advanced air-defense systems, allowing for precise targeting and rapid beam steering.12
