Abstract：A novel patch array antenna integrating radiation characteristics and scattering characteristics is proposed.The proposed patch antenna array consists of two kinds of patch structures with 180° phase difference,and the coding mode of the array factor with the minimum maximum value in the reflection do-main is calculated by genetic algorithm using the feature pattern analysis,so that the two kinds of antenna units are arranged into a 4×4 antenna array according to their mode.The antenna array-10 dB imped-ance bandwidth is 8.1～9.2 GHz(12.7％relative bandwidth),and the peak gain is 18.7 dB in the operat-ing band;more than 6 dB of single-station RCS reduction under x-polarized incident wave is achieved in the wide band 6.9～10.5 GHz(41.4％).The stealth function of the antenna is realized without introducing additional structures and collector elements.
