Abstract
In this paper, several theoretical analysis methods, transmission line model theory, cavity model theory and integral equation method for circular waveguide circular polarization converters are introduced. In the third chapter, we discuss the circular polarization theory of circular waveguide circularly polarized converters, the properties of circularly polarized waves, and how to realize circular polarization. The circular polarization of single-point feeding and double- converter. The fourth chapter discusses the circular wave conductor and the technique of circular waveguide circular polarization converter, and describes a variety of methods to realize and round the waveguide.
In the fifth chapter, we discuss the design of circular polarization converters. Based on the basic theory described in the previous section, three methods of circularly polarized circular waveguide circular polarization converters are discussed. The design of circularly polarized circular waveguide circular polarization converters is discussed emphatically. Through the comparison of the three methods, the feed mode is more advantageous than the other two, and finally the feed converter is fabricated. Through the actual measurement, the bandwidth of 2.9GHZ to 3.3GHZ is successfully realized, In the range of good standing wave characteristics and radiation characteristics.
