摘　　要：该文对一个共形在非规则曲面上的H形微带阵列进行了优化及设计。采用自适应混合遗传算法对此共形阵列的辐射方向图进行了优化设计。优化后的辐射方向图在水平方向几乎达到了全向辐射,俯仰面方向图集中辐射在水平方向。最后考虑到相位误差,对优化结果进行了误差分析。结果表明,该文所提出的优化算法对于非规则曲面上共形阵列的设计是有效和可行的。An H-shaped conformal microstrip antenna array mounted on an irregular curved surface is optimized and designed in this paper and the radiation pattern of this conformal array is synthesized using the Self-adaptive Hybrid Genetic Algorithms （SHGA）. The optimized azimuth radiation pattern of the conformal array is almost omnidirectional and the elevation radiation pattern is concentrated in the horizontal direction. Finally,the optimized results are analyzed in view of the phasic error. The results show that the proposed procedure is an effective and feasible method for designing the conformal antenna array on an irregular curved surface.
