摘　　要：设计了一种微带馈电具有双频陷波特性的超宽带天线。通过在梯形贴片上开C形缝隙,在馈线上开π形和回形缝隙实现WiMAX和WLAN频段的双陷波特性,并建立适当的神经网络模型辅助分析,以提高设计效率。仿真和实测结果表明,该天线具有较好的陷波特性且陷波阻带具有良好矩形度,能有效避免超宽带通信系统与带内其它无线通信系统之间的干扰。A antenna fed by microstrip line with two band - notched characteristics is presented. The dual band - notched characteristic of WiMAX and WLAN spectrum is realized by adding a C - shaped slot on the radiator patch and ir - shaped and Hui - shaped slots on the feed line of the proposed antenna. To improve the design efficiency, the neural network is a- dopted in the process of auxiliary analysis. The simulation and measurement result shows that the proposed antenna has good characteristic of band - notched and high rectangularity of stop band. Besides, it can avoid the interference between ultra - wideband communication system and other wireless communication system efficiently.
