单馈圆极化微带天线的工程调试方法研究

内容简介：为解决单馈圆极化微带天线的工程实现与设计方案存在着谐振频点不一致、轴比变差等问题，基于单馈圆极化天线理论基础，提出了两类单馈圆极化天线的工程调试方案，并采用HFSS软件进行了仿真。仿真结果表明，在天线的不同位置进行调试可分别对单馈圆极化微带天线的谐振频率、反射系数和轴比等天线性能进行优化调整，这对该类天线的工程调试具有指导意义。

Abstract：To solve the problems that resonant frequency points are inconsistent and the axial ratio is getting worse between the engineering implementation of the single-feeding circularly polarized micro-strip antenna and its design scheme, this paper puts forward two kinds of engineering debug schemes for this micro-strip antenna and simulates them using HFSS software, based on the theoretic basis of single-feeding circularly polarized micro-strip antenna. Simulation results illustrate that the resonant frequency, reflection coefficient and axial ratio as well as other performances of the micro-strip antenna can be optimized respectively by debugging at various positions of this antenna, which plays a certain guiding role in engineering debug of these kinds of antenna.
