【摘要】 提出一种针对复杂需求天线的高效优化方法.首先分析人们对天线的常见需求,然后定义了一些通用的目标单元用于实现适应度函数的快速构造.大部分复杂的天线需求都可以通过对这些目标单元进行组合从而精确的表达出来.这样不仅可以提升算法对天线方案的评估精度,还可以大大增加算法的通用性和可扩展性.为了进一步提高优化效率,一种改进的差分进化算法被提出从而提高算法的搜索速度.最终的实际应用案例说明:用这种方法优化出的天线的各项指标都满足实际需求.更多还原

【Abstract】 A general optimization method for complex requirement antennas is proposed.First,the common requirements of antennas are analyzed.Then some general objective units are defined to construct the fitness function quickly.Most of the antenna requirements can be accurately expressed by these objective units,which not only can improve the evaluation accuracy of the design scheme but also can significantly enhance the generality and scalability of the algorithm.To further improve the optimization efficiency,an improved differential evolution algorithm is designed,which can speed up the convergence rate.The actual case shows that the indicators of the antenna optimized by the proposed method can meet all the requirements.更多还原
