Considering The Mutual Coupling Waveguide Unit Infinite Phased Array Analysis And Design

In this thesis, waveguide element infinite phased-array antennas has been analysised and designed by integral equation method and mode matching method. First, the integral equation of an infinite phased array of rectangle waveguide with rectangle grid was deduced and its solution by moment method was presented either. And then, another applied widely analysis method - mode matching method was introduced. Following, the paper represented the analysis method of triangle grid phased array. Moreover, the infinite phased array with WAIM (added with metallic iris plate on each aperture of waveguide element and covered with dielectric sheet) in front of the array was analysised and its property of wide-angle matching was studied, too.The computational examples show the reflection characteristics and the radiation characteristic of rectangle waveguide infinite phased arrays with rectangle grid or with triangle grid. At the same time, characteristics of the same constitution array but covered with iris plate and dielectric sheet are computed. The algorithm's validity is verified by above computational examples. The computational result can be applied in project.Separately, the above examples are operated by simulation post treatment method with HFSS simulator. Comparison and analysis among software imitating results, program imitating results and literature results are exhibited.
