[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.
