| This thesis mainly analyzes the coaxial probe-fed microstrip antenna and studies the broadband microstrip antenna. By equalizing the three-dimension current source to the two-dimension current source in spectral domain, the coaxial probe-fed microstrip antenna is analyzed with the full wave method and moment methods is used to numerically analyze the integral equation. The thesis deeply analyzes the factors which affect the bandwidth of microstrip antenna and studies the influence of coaxial probe which is applied to feed to microstrip antenna. The systemic method of designing microstrip antenna is presented. The broadband dual-patch microstrip antenna is studied with the help of the simulation software and some conclusions are obtained. At last, the broadband microstrip antenna is manufactured successfully. |
