摘　　要：设计了一款基于超材料的双陷波小型化超宽带天线。在半圆形单极子超宽带天线基础上,通过在辐射单元引入超材料结构来改善超宽带天线的性能,实现了小型化和双陷波特点。研究表明,小型化超宽带天线在加入超材料结构后,天线尺寸减小了19%,并在4. 2、6. 1 GHz处达到了双陷波功能,该天线在超宽带通信系统中有潜在的应用价值。In this paper,a dual notch miniaturized UWB antenna based on metamaterials is designed and studied.Based on the semicircular monopole UWB antenna,the performance of UWB antenna is improved by introducing metamaterial structure into the radiation unit,and the miniaturization and double notch baud point are realized. The research shows that the size of the miniaturized UWB antenna decreases by 19% after the addition of metamaterial structure,and the dual-notch wave effect is achieved at 4. 2 GHz and 6. 1 GHz. This antenna has potential application value in UWB communication system.
