Abstract: Based on the miniaturization of the anti-jamming array antenna, a new technique for beamforming is proposed. In the actual design, the array antenna is miniaturized by reducing the spacing between array antenna elements; the HFSS VBScript script is programmed to extract the active pattern and active impedance data of array elements; the optimization based on the differential evolution algorithm is written in Matlab; HFSS is called by Matlab for full-wave simulation analysis, and the optimal element weighting factors are obtained to achieve the pattern null of the anti-jamming array antenna. Research results show that this technique can form pattern null in the interference direction (30°,10°)very accurately, and that the null depth  increases by 32dB.
