A Study of the field distribution in focal plane for the shape deformations of Satellite antenna

위성 반사경 안테나 변형으로 인한 초점영역의 전자장 분포에 관한 연구

The main purpose of this paper is to determine a new focal point and field distribution due to the shape deformation of reflector antenna by numerical method such as geometrical optics and the aperture field method. It is shown the 4 types deformations to be added into original shape of parabola antenna and offset antenna: linear, quadratic, cubic and hybrid distortion. These results can be applied to deformed reflector antenna in order to fit a focal point and radiation pattern.
