Then the third chapter discusses the theory of the circular polarization microstrip antenna, the nature of the circular polarized wave, and how to implement circular polarization, focus on single point feed are discussed, the two point circular polarized antenna feeder. The fourth chapter discusses the broadband microstrip antenna and miniaturization, tells the story of a variety of ways to realize miniaturization and wide band. This article discussed in chapter 5 small circular polarized antenna design. Utilizing the basic theory, mentioned in the previous section discussed the three method can realize the circular polarization microstrip antenna, of aperture coupled feeding is mainly discussed in the design of the circular polarization microstrip...
