摘要

设计了一种新型的六陷波超宽带天线。通过在辐射贴片上添加一个T形谐振枝节、一个弯枝节，开一个U形槽，馈线附近引入C形枝节、反C形枝节和在地板上开一对对称的L形槽，实现了六陷波特性，有效地抑制了窄带系统和超宽带系统之间的相互干扰。研究了所加入结构对天线陷波特性的影响，通过天线表面电流分布和等效电路解释了陷波的原理，最后将天线加工成实物。实测的驻波比、方向图和增益与仿真结果基本吻合，证明了设计方法的正确性。所设计的天线性能优良，六陷波特性大大提高了天线的应用范围。

Abstract

A novel sextuple band-notched UWB antenna was designed. Sextuple band-notched characteristics could be realized by adding a T-shaped stub

a bent stub

and etching a U-shaped slot on the patch

adding a C-shaped stub

an anti-C shaped stub near microstrip line and etching a pair of L-shaped slots on the ground plane

which effectively sup-presses the interference between narrow band systems and UWB systems. The influence of the proposed structures on band-notched characteristics was studied

and band-notched principle was explained by antenna surface current and equivalent circuit. Finally the antenna was fabricated and measured. The measured results of VSWR

radiation patterns and gains agree well with the simulated results

which demonstrates the correctness of the design method. The proposed antenna has good performance and can be widely used due to its sextuple band-notched characteristics.
