A new pattern synthesis technique which uses Genetic Algorithm to optimize antenna arrays shaped-beam patterns is proposed in this paper. Given the determinate number and space between the antenna arrays units, the feeding-back amplitudes and phases are optimized and selected by this way to make the shaped-beam patterns satisfy the designing request . This paper solves the key technique and way to apply Genetic Algorithm to antenna arrays shaped-beam patterns , proves it by experiment. There is good agreement between the desired and calculated radiation patterns. All these show the abroad application foreground of Genetic Algorithm in antenna designing.
