摘　　要：针对未来智能终端的体积小、多网融合特性,基于分形和仿生天线理论,借鉴自然界中铜钱草的圆环结构,采用分形结构和共面波导馈电技术,设计了一款结构新颖、多频段共面波导馈电小型天线。设计中采用HFSS软件进行建模仿真,通过对天线辐射体中圆环叶片个数和半径大小的变化、接地板形状及尺寸的优化,最终确定天线相关最佳参数,采用AV3629B矢量网络分析仪对天线实物进行性能测试。仿真和测试结果表明,该天线在覆盖的1.11~1.55 GHz、2.34~2.59 GHz、3.49~5.83 GHz频段内具有良好的辐射特性,可通用于TD-LTE专网宽带集群、卫星通信、4G/5G公众网、蓝牙、WLAN等通信系统。According to the small size and multi-network convergence for smart terminals in the future,based on fractal and bionic antenna theory,imitated the ring structure of the hydrocotyle chinensis(Dunn)craib,utilized fractal structures and CPW technology,a multi-band CPW fed antenna is proposed.HFSS software is used to construct,simulate the antenna model,scanning analyses of the number of iterations of rings and different sizes,ground plate shape and size are carried out.The detailed parameters of the antenna are determined.The antenna is tested by the AV3629B vector network meter.Simulation and measurement results show the antenna can cover the following bands:1.11-1.55 GHz,2.34-2.59 GHz,3.49-5.83 GHz.In the above frequency bands,the antenna has good radiation characteristics.The antenna can be commonly used in TD-LTE private network broadband cluster,satellite communication,4G/5G public network,Bluetooth,and WLAN.
