Phased Antenna Array
In the context of aerospace engineering, a Phased Antenna Array is a multiple-antenna system that transmits or receives radio waves in a directional manner. This system is designed to direct the beam of radio waves in a specific direction, allowing for more precise communication with spacecraft or satellites. The 'phased' part of the name refers to the phase of the radio waves, which can be adjusted to steer the beam. This is achieved by altering the relative phase of the signal at each antenna, which changes the direction of the overall wavefront. The array can be used to form multiple beams, known as 'beamforming', or to focus a single beam on a specific location, known as 'beamsteering'. This technology is crucial in aerospace engineering as it allows for more efficient and reliable communication with spacecraft, even over vast distances.
