Parametric design of Cassegrain parabolic reflector antenna

In this study, various studies were performed on the structure of a Cassegrain-type parabolic reflector aIntenna which is commonly used in space research and satellite communication systems. The first attempted is to define and optimize the structure of the horn antenna and its near-field radiation, to fall on the sub reflector created in the framework of an EM field. This sub reflector positioned into the frame structure of the main reflector in the same way with a near fall on the more established framework. In the end the main reflector on a very narrow beam reflected from the EM field Cassegrain main reflector radiation pattern is obtained. In this study, the reference horn antenna, the location and size of the sub reflector and the main reflector structure optimizations tried to get the best results. In this context, the ARM method is used to solve electromagnetic problems, this method is selected and compared with other analytical and numerical methods and had been presented in the next chapters.In the first chapter of the study analytical and numerical methods are discussed brieflyin the second chapter, the formulations of ARMs are explained generally.The third chapter is the design of feed antenna, a horn antenna is chosen as our feed antenna structure in this chapter the phases of our design will be described briefly.İn the fourth chapter, parabolic reflector antenna structure and its design will be described after that the cassegrain parabolic antenna design and optimizations is explained.The fifth and final chapter is summary and comments of the designed and optimized Cassegrain-type parabolic reflector antenna.
