摘要：
This letter introduces a novel technique for low radar cross section (RCS) antenna designs. The differential evolution algorithm (DEA) and the method of moments (MoM) are combined to achieve the RCS reduction and satisfied radiation performance. The antenna geometric parameters are extracted to be optimized by DEA, and a fitness function is evaluated by MoM to represent the performance of each candidate design. The optimization example of the slot patch antenna is presented as a test of the proposed DEA/MoM algorithm. By optimizing the slot location, the given slot antenna realizes the RCS reduction in the broad frequency range of 2-12 GHz at different incident angles, which demonstrates the feasibility of applying the proposed method to antenna RCS reduction.
