Variable Polarization System And Polarized Microstrip Antenna

In this thesis, the variable polarization technique is introduced into the radio fuze system, in order to improve the system's anti-jamming ability. Based on the discussing of the polarization theory, polarization-agile theory and microstrip antenna design theory, we study the variable polarization transceiver structure and the dual-polarized microstrip antenna. A scheme of variable polarization system is proposed, and its anti-jamming principle is analysised. With the help of the full-wave simulation IE3D, we design, simulate and study the dual side-fed dual-polarized square patch antenna. The effects of the substrate thickness and the relative dielectric constant are also discussed. Then, based on the study of the microstip antenna array, two types of 4 units dual-polarized microstrip antenna array are designed, and compared they differences and samenesses.At last, designed a 16 units dual-polarized microstrip antenna array.
