摘要
设计一款新型的具有双陷波特性的超宽带(Ultra Wide Band,UWB)天线。该天线通过在辐射单元中开π型槽和集成电磁带隙(Electromagnetic Band Gap,EBG)结构,实现了在3.06~13.6 GHz频带上的驻波比(Voltage Standing Wave Ratio,VSWR)小于2,也可以抑制3.3~3.7 GHz(WiMAX频段)、7.50~8.50 GHz(卫星X波段)的VSWR。设计的天线经过高频电磁仿真软件(High Frequency Structure Simulator,HFSS)仿真和优化后,得到了比较理想的回波损耗、增益以及良好的辐射方向图。最终的仿真结果表明,该天线能够较好地应用于超宽带系统中。
In this paper,a new Ultra Wide Band(UWB)antenna with double notch characteristics is designed.By openingπ-shaped slots in the radiation unit and integrating Electromagnetic Band Gap(EBG)structure,the antenna can achieve a Voltage Standing Wave Ratio(VSWR)of less than 2 in the 3.06~13.6 GHz band,and can also suppress VSWR of 3.3~3.7 GHz(WiMAX band)and 7.50~8.50 GHz(satellite X-band).After High Frequency Structure Simulator(HFSS)simulation and optimization,the designed antenna has obtained ideal return loss,gain and good radiation pattern.The final simulation results show that the antenna can be well used in UWB system.
