Dynamic Thinning of Antenna Array Using Differential Evolution Algorithm

Dynamic thinning is a process by which the total number of active elements in an antenna array is reduced under real time conditions without causing major degradation in system's performances. This paper suggests a technique by which a thinned antenna array is designed by simple differential evolution(DE) algorithm overcoming the difficulties of large and rugged solution space and slow rate of convergence in case of large 2-D arrays.
