基于HFSS的圆极化微带天线的设计和仿真
内容简介：设计了一种圆极化微带天线,采用表面开槽的方法来减小天线的尺寸和提高天线的整体性能,介质基板采用高介电常数的材料,通过选择适当的馈电位置和切角实现圆极化工作方式,利用HFSS软件对天线进行了电磁仿真和物理建模,优化了天线的各项参数,得出了驻波比、增益、轴比等仿真曲线。仿真结果表明,天线的增益和方向图特性良好,天线的尺寸明显减小,满足工程需要。
Abstract：This design of a circularly polarized microstrip antenna,using slotted surface of the ways to further reduce the antenna size and improve the overall performance of the antenna,high dielectric constant of dielectric substrate materials,by selecting the appropriate feed location and notching work to achieve circular polarization,the antenna using HFSS software for electromagnetic simulation and physical modeling,optimizing the parameters of the antenna,obtained VSWR,gain,axial ratio and other simulation curve.Simulation results show that the antenna gain and pattern characteristics of a good,significantly reduced the size of the antenna to meet the project needs.
