Abstract :
In order to meet wide angle scanning requirements of the satellite antenna, a side-fed parabolic torus reflector antenna is designed in this paper. The ellipsoid is adopted as sub-reflector with the purpose of reduction the mechanical equipments. The sub-reflector is rotated in azimuth to scan the antenna beam in the direction (±20°) for wide swath coverage. The calculated results guiding the antenna optimization are based on physical optics (PO) analysis and agree well with our design goals.
