Aperture Arrays

Aperture arrays are collections of multiple small antennas working together to receive or transmit radio signals. Instead of a single large antenna, an aperture array uses many smaller elements arranged in a pattern, which can be electronically adjusted to shape the signal’s focus and direction. This setup allows for rapid steering of the beam without physically moving the antennas, offering flexible and precise control. Aperture arrays are used in radar, radio telescopes, and wireless communications, providing enhanced sensitivity, wider coverage, and improved ability to track multiple signals simultaneously.
