摘　　要：随着5G通信技术的快速发展,对于跨频段组网有了更高的要求,多频段天线的高效优化成为重点。传统的空间映射方法对天线进行优化时,要准确地建立一个与之相对应的等效电路模型是非常困难的,因此寻找一种简单快速的方法来建立可靠的粗模型至关重要。通过响应面近似算法来构造粗模型,解决了传统优化方法建立等效电路的困难,进一步节省了计算时间。最后,通过使用流形空间映射算法优化单层跨频段双频天线的设计实例,证明了该方法的可行性。With the rapid development of 5g communication technology,there are higher requirements for cross-band networking,and the efficient optimization of multi-band antenna becomes the focus.When the traditional space mapping method is used to optimize the antenna,it is very difficult to accurately establish a corresponding equivalent circuit model,so it is very important to find a simple and fast algorithm to establish a reliable rough model.The rough model is constructed by response surface approximation algorithm,which solves the difficulty of establishing equivalent circuit by traditional optimization method,and further saves calculation time.Finally,by using the manifold space mapping algorithm to optimize the design of a singlelayer cross-band dual-frequency antenna,the feasibility of this method is proved.
