| 摘 要： | 介绍了一种新出现的Taguchi全局优化算法,并将其应用于双层贴片宽带天线的输入阻抗带宽优化设计中.Taguchi算法基于正交矩阵对参数空间的均匀抽样,以较少的计算量就能评估参数对结果的影响,通过多次迭代并缩小搜索级差,从而实现快速的多参数全局优化,其具有实现简单、收敛快等优点.以天线的反射损耗S_(11),在期望带宽范围内的积分作为目标函数,对含有7个变量参数的双层贴片天线结构进行了优化设计,优化进程经过40次迭代后得到了求解精度内的最优解,优化得到的双层贴片天线VSWR<3的带宽达到40%,对宽带电磁脉冲的辐射因子增益达到1.4. |
| 关 键 词： | Taguchi算法 双层贴片 全局优化 宽带天线 宽带电磁脉冲 |

| Abstract: | A novel global optimization method for two-layer patch wideband antenna based on Taguchi's algorithm is performed in this paper. Taguchi's algorithm is based on OA array concept,an optimal evenly distribute in multi-dimensional parameters space. By employing an OA(18,7,3,2)and well designing fitness function,which is the integration of the antenna port reflect parameter S11 in expect frequency band,a two layer patch antenna contains seven variable dimension parameters was optimized around 500 MHz centre fre... |
