摘要(Abstract)：
设计一种基于缺陷地结构(DGS)的三角形微带天线,通过在三角形贴片表面和三角形接地面上分别嵌入冰晶状槽和DGS实现双频操作,同时增加了天线的带宽,并使用Ansoft HFSS软件对天线进行仿真,天线覆盖Wimax 3.5/5.5 GHz两个频段,对应的10 dB回波损耗带宽分别是9.1%(3.36~3.68 GHz)和1.8%(5.45~5.55 GHz)。此外,通过对介质基板的形状进行比较后发现,与通常使用的矩形介质基板相比,三角基板具有更好的阻抗带宽和更小的体积。最后,对天线进行加工和测试,在3.5 GHz和5.5 GHz频段对应的实测带宽是8%(3.38~3.66 GHz)和1.6%(5.44~5.53 GHz),测试与仿真结果基本一致。
