| 摘 要： | 设计了一种小型三陷波平面超宽带天线,通过在天线的辐射贴片上加载U形缝隙、在接地板上开一对对称的L形缝隙和引入寄生条带,使得天线在3.2～3.6GHz、3.7～4.3GHz和5.3～6GHz频段内实现频率阻断。利用仿真软件研究了U形缝隙、L形缝隙和寄生条带对陷波特性的影响,并对所设计的超宽带天线进行了制作和测量。结果显示,该天线在工作频段2.8～10.6GHz内具有良好的辐射方向特性,能广泛应用于超宽带系统。

| Abstract: | A compact planar ultra-wideband antenna with triple band-notched characteristics is proposed.U-shaped slot in the radiating patch,a pair of L-shaped slot and one parasitic strip on the ground are utilized to achieve the triple band-notched characteristics within the frequency range between 3.2～3.6 GHz, 3.7～4.3 GHz and 5.3～6 GHz.Effects of the U-shaped slot,L-shaped slot and the parasitic strip on the antenna band-notched characteristic have been studied using simulation software,and the proposed antenna is also fabricated and measured.Results indicate that the proposed antenna has good radiation performance over the entire frequenc range from 2.8～10.6 GHz and can be widely used in UWB system. |
