摘　　要：本文提出了1种采用共面波导馈电的双陷波特性超宽带平面天线,通过在单极子辐射贴片上蚀刻U形槽,并在辐射贴片两端加载弧形寄生枝节,实现了在WiMAX(3.3~3.6GHz)和WLAN(5.15~5.825GHz)2个频率段的陷波目标,且该天线尺寸仅为31mm×30mm×1.5mm。最终的仿真结果表明:天线具有2.4~10.7GHz的工作带宽,满足超宽带通信要求,在3.18~3.82GHz和5.10~6.05GHz2个频段具有良好的陷波情况,能有效抑制WiMAX和WLAN的干扰。In this paper,a dual band-notched UWB planar antenna fed by coplanar waveguide is proposed.By etching U-shaped slots on the on the radiating patch of the monopole antenna and loading arc parasitic branches on both sides of the radiating patch,the notched targets in WiMAX(3.3~3.6GHz)and WLAN(5.15~5.825GHz)are realized,and the antenna size is only 31mm×30mm×1.5mm。The final simulation results show that the antenna has a bandwidth of 2.4~10.7GHz,meets the requirements of ultra-wideband communications,and has good notch performance in 3.18~3.82GHz and 5.10~6.05GHz,which can effectively suppress the interference of WiMAX and WLAN.
