摘要
设计一种结构新颖紧凑的小型宽频带(带宽10 GHz)微带天线。以24 mm×23 mm×1.6 mm的FR4为基底,在基底接地面中心位置设计一个正六边形和一个对称的十字交叉型贴片组成的缝隙来增大工作带宽,基底另一侧是一条微带线。用电磁仿真软件Ansoft HFSS对该天线进行模型仿真和结构优化,并进行加工和测试。结果显示该天线工作频段覆盖3.6~13.6 GHz,阻抗带宽为116%,辐射特性良好,给出了反射损失曲线和辐射方向图,测试结果与仿真结果基本相同,为宽频带无线通信的研究提供了一定的参考。
A novel compact minitype broadband microstrip antenna working in 10 GHz broadband is designed,which takes FR4 with the size of 24 mm×23 mm×1.6 mm as its substrate.A slot composed of regular hexagon and symmetrical cross type patches is designed in the center location of substrate ground plane to enlarge the working bandwidth.The microstrip line is located in the opposite side of the substrate.The electromagnetic simulation software Ansoft HFSS is used to perform the model simulation and structure optimization for the antenna.The antenna was processed and tested.The results show that the working bandwidth of the antenna covers the range of 3.6~13.6 GHz,the impedance bandwidth can reach up to 116%,and the antenna has perfect radiation characteristic in the frequency band.The reflection loss curves and radiation pattern are given.The test results are basically the same with simulation results.The design provides a certain reference for the study on broadband wireless communication.
