Implementation Methods for Planar Wide-Angle Scanning Phased Array

Wide-angle scanning phased arrays are hotspots and difficulties in the research field of phased arrays in recent years. Since 2009, Computational Electromagnetic Laboratory (CEMLAB) at University of Electronic Science and Technology of China (UESTC) has carried out related research work, and proposed a theoretical and experimental scheme to break the bottleneck of the limitation of phased array scanning angles by using the pattern reconfigurable technique. Subsequently, CEMLAB conducted in-depth research and gradually developed theoretical methods based on the electromagnetic mirror principle, surface wave assisted method, magnetic current source technique or time reversal (TR) adaptive optimization method to realize planar phased arrays with wide-angle scanning performance. At last, the development trend of wide-angle scanning phased arrays is predicted in the conclusions.
