我们提出了一种紧凑的平面超宽带（UWB）天线与3.4/5.5 GHz的双陷波特性。该天线由一个倾斜的矩形金属贴片和一个50 Ω共面波导（CPW）传输线。通过在贴片中蚀刻两个嵌套的C形槽，实现了WiMAX/WLAN频带中的带阻滤波特性。所提出的天线成功地模拟，设计和测量显示宽带匹配阻抗，稳定的辐射方向图和恒定的增益。提出的天线的等效电路模型，讨论了双陷波UWB天线的机制。文中还介绍了一种超宽带天线和一种单陷波天线。
We propose a compact planar ultrawideband (UWB) antenna with 3.4/5.5 GHz dual band-notched characteristics. The antenna consists of a beveled rectangular metal patch and a 50 Omega coplanar waveguide (CPW) transmission line. By etching two nested C-shaped slots in the patch, band-rejected filtering properties in the WiMAX/WLAN bands are achieved. The proposed antenna is successfully simulated, designed, and measured showing broadband matched impedance, stable radiation patterns and constant gain. An equivalent circuit model of the proposed antenna is presented to discuss the mechanism of the dual band-notched UWB antenna. A UWB antenna and a single band-notched one are also provided for references.
