本文从控制网络输入端口反射系数出发，提出了一种最小失配的宽带天线匹配网络的设计方法。利用精英保留非劣排序遗传算法分别设计了最小失配的天线无耗匹配网络和有耗匹配网络，实现网络输入端口反射系数和传输功率增益的多目标优化，并对匹配网络的传输函数对负载变化的灵敏度进行了分析。仿真实验表明，所设计的最小失配的匹配网络具有随负载变化灵敏度小的优点，证明了该方法的有效性。

英文摘要：

The paper evaluated the network input reflection, and proposed a design method of broadband antenna matching network based on minimum mismatch theory. The lossless and lossy of minimum mismatch antenna matching net- work were designed by utilizing Non-dominated Sorting Genetic Algorithm II. Multi-objective optimization of the input reflec- tion and the transmission power gain were realized. The sensitivity of matching network transfer function with varying load was analyzed. Simulation results showed that the minimum mismatch antenna matching network has the advantage of being less sensitive to the variation of load, and proved the validity of this approach.
