| 摘 要： | 提出了一种由双层不均匀频率选择性表面(FSS)结构组成的领结型高增益天线,对其进行了仿真分析。结果显示该天线在不加外匹配网络情况下,|S11|≤–6 dB的阻抗带宽可达到72%,同时有很好的辐射方向图。与均匀频率选择性表面组成的天线相比较,该不均匀性天线带宽为均匀频率选择性表面组成的天线的1.5倍,并且仍然保持低轮廓。这种特性适用于点对点弱信号通信。

| Abstract: | A high gain bowtie antenna consisting of double layers non-uniform frequency selective surface(FSS) was proposed and analyzed by simulation.Results show that 72% of the impedance bandwidth of the antenna for |S11|≤-6 dB can be obtained without additional matching network,and the well-behaved radiation patterns are displayed.Compared with the uniform one,the bandwidth of the antenna increases 1.5 times,which keeps a low profile.It is suitable to use in point-to-point weak signal communication. |
