In order to solve problem of grating lobes suppression for ultra-wideband phased array antenna,an efficient fitness function calculation method based on genetic algorithm is developed. Through optimizing spacing of elements of phased array antenna,grating lobes suppression for ultra-wideband（ 8- 18 GHz） phased array antenna is implemented. Effectiveness of the algorithm is proved by comparing frequency response curve of the phased array with optimized elements spacing and that of phased array with the same element spacing and same length of array.
