摘要
设计了一种新颖的具有双陷波特性的新型超宽带天线。通过在径向贴片上添加弧形寄生单元和馈线上刻蚀U型槽相结合的方法实现天线的双陷波特性。利用仿真软件对天线不同参数进行仿真分析得到了天线的最优尺寸。并且结合加入陷波结构前后天线表面电流分布与输入阻抗曲线得到了天线的等效电路,定性地解释了陷波特性的工作原理。仿真和测试结果表明,天线在通带2.54~11.22GHz的频段范围内满足电压驻波比小于2,在WiMAX和WLAN两个频段内实现了良好的陷波特性,且尺寸小、辐射特性良好,对超宽带系统的应用具有一定的参考价值。
A novel dual band-notched ultra-wideband antenna was designed.To generate the dual band-notched characteristic,an arc parasitic element was added on the radial patch and a Ushaped slot was etched on the feeder.Simulating and analyzing the different parameters by simulation software,the optimal size of the proposed antenna was obtained.By combining the input impedance curve and the surface current form of the antenna before and after adding the notch structure,the working principle of the notch characteristics was explained qualitatively.The simulated and measured results show that the proposed antenna yields a voltage standing wave ratio（VSWR）of less than 2 in the passband range of 2.54 GHz to 11.22 GHz,and it has good dual band-notched characteristics in the bandwidth of WiMAX and WLAN.Moreover,it has small size and good radiation characteristics,which has certain reference value for the UWB application.
