Antenna Array

Antenna arrays, collections of multiple antennas working together, aim to enhance signal transmission and reception by manipulating wave interference patterns. Current research heavily focuses on optimizing beamforming techniques, often employing machine learning models like neural networks and Gaussian processes to improve accuracy and robustness in diverse environments, including mitigating interference and adapting to hardware limitations. These advancements are crucial for enhancing the performance of 5G and future 6G wireless communication systems, as well as improving the efficiency and reliability of satellite communication and radar systems. The development of efficient calibration methods and improved codebook designs are key areas of ongoing investigation.
