A novel hybrid IWO and CS algorithm for phase-only pattern synthesis of large array antenna

In this paper, a novel hybrid Invasive Weed Optimization (IWO) and Cuckoo Search (CS) algorithm (IWO/CS) is presented for phase-only pattern synthesis of large array antenna. The IWO/CS embeds the Levy flight CS into IWO as global guide, thereby enhancing search ability algorithm. At same time, in order to avoid trapping local optimal solution, mutation operator introduced enhance Finally, competitive exclusion operation improved maintain diversity population. applied beam shaping achieve main lobe broadening side depression. Simulation results demonstrate superiority
