Abstract An integralization design method in the antenna and feed system of active phased array for low side lobe is presented in this paper. From some main rsepects detail how to do the integral design. Some experiments have been done on the 2×48 elements antenna array. The measured peak side lobe level and the zero depth of the difference pattern are all lower than -31dB. When the pattern scan to ±60°, the peak side lobe level is not higher than -26.5dB. It is shown that the integralization design is necessary.
