摘 要：微带天线具有体积质量轻，制造简单方便，易于集成等特点，因此被广泛应用于雷达、卫星通信、无线通信装置等领域。圆极化微带天线是微带天线的重要研究方向之一，旨在利用圆极化波的灵活性，并减小信号的多路径干扰。
本课题主要介绍了微带天线的发展史，叙述了微带天线基本理论及设计方法，并介绍了单馈点和多馈点(双馈点)圆极化微带天线设计方法。因为单馈点天线结构较为简单，本课题选择了单馈点进行右旋圆极化矩形微带天线设计，用Ansoft HFSS对其建模仿真，并对结果进行了分析。

Design of the right-handed circular polarization rectangular microstrip antenna
Abstract：Microstrip antennas are widely applied in radar, satellite communication, wireless communication devices and other fields because of their characteristics such as small volume, light weight, simple and convenient to manufacture and easy to integrate. Circularly polarized microstrip antenna is one of the important research directions of microstrip antennas, which aims at utilizing the flexibility of circular polarized waves and reducing the multipath interference of signals.
This topic mainly introduces the development history of microstrip antenna, describes the basic theory and design method of microstrip antenna, and introduces the design method of single feed and multi feed point (doubly fed point) circular polarized microstrip antenna. Because of the simple structure of the single feed point antenna，it is chosen to design the right-handed circular polarization rectangular microstrip antenna. And then we use Ansoft HFSS to make the simulation model. At last, we analyze the results.
The dissertation has 19 pictures, 0 tables and 18 references.
Key Words: circular polarization; microstrip antenna; feeding point
