【摘要】：首先,阐述了论文的研究背景和意义,并介绍了八木天线国内外研究现状。接着论述了天线的基本特性和基本参数,第三章介绍了八木天线的基本理论,重点介绍了八木天线的各个振子对八木天线方向图的影响。最后对准八木型微带天线进行了设计和制作,通过增加引向器数量和参数的优化,使准八木型微带天线实现了高的增益和相对较宽的带宽。天线的实测结果与仿真基本一致。通过实验验证了微带结构中,八木天线同样可以通过增加引向器数量来改善天线方向性,并且能够实现相对较宽的带宽。同时还讨论了准八木型微带天线的结构和其他各参数对天线性能的影响。
[Abstract]:Firstly, the research background and significance of the thesis are described, and the research status of Yagi antenna at home and abroad is introduced. Then the basic characteristics and parameters of the antenna are discussed. In the third chapter, the basic theory of the Yagi antenna is introduced, and the influence of each dipole of the yagi antenna on the pattern of the Yagi antenna is emphasized. Finally, the Yagi microstrip antenna is designed and fabricated. By increasing the number and parameters of the pilot, the quasi-Yagi microstrip antenna can achieve high gain and relatively wide bandwidth. The measured results of the antenna are in good agreement with the simulation. The experimental results show that the Yagi antenna can improve the antenna directivity by increasing the number of directerers and realize a relatively wide bandwidth in the microstrip structure. At the same time, the structure of quasi-octagonal microstrip antenna and the influence of other parameters on the antenna performance are discussed.
