摘　　要：将空间映射算法推广到共形天线的优化设计之中,并设计了一个谐振频率在2.5GHz的柱面矩形贴片天线。粗糙模型和精细模型分别采用腔模理论和全波电磁仿真软件HFSS进行分析,并通过渐进空间映射算法联系起来。计算结果表明,与直接优化精细模型相比,该方法可以大大减少计算时间,提高设计效率。Space Mapping Algorithm is used in the optimized conformal antenna and the cylindrical-rectangular patch antenna with resonant frequency 2. 5 GHz is designed. We exploit the cavity-model theory as the coarse model and electric magnetic simulation software HFSS as the fine model, they are aligned through Aggressive Space Mapping Algorithm. The result shows it needs less calculation time and increases the design efficiency comparing with only optimizing the fine model.
