| 摘 要： | 在馈源终端引入自相似性分形结构,提出了一种新型的抗干扰宽带微带天线。采用电磁仿真软件Ansoft HFSS对分形馈源对驻波的影响和电流分布进行了仿真与讨论,获得了约116%的阻抗带宽(VSWR≤2),频率范围是1.66 GHz~6.20 GHz,比文献[3]中没有做分形结构处理的天线展宽了200 MHz带宽。分别给出了2 GHz和5 GHz频点的计算方向图,方向图在频带内基本相同。

| Abstract: | A broadband fractal antenna in antijamming equipment is presented,which is fed by a new self-similar fractal structure on terminal feed.By using Ansoft HFSS,some studies of fractal feed are discussed on impedance bandwidth and current distribution.Its VSWR≤2 bandwidth reaches approximately 116%,covering 1.66 GHz~6.20 GHz,which is wider than the results of Ref[3] about 200 MHz.The radiation patterns of the antenna at 2 GHz and at 5 GHz are both presented and it is seen that the discrepancies between them are... |
