Abstract :
Two antenna designs for the five hundred meter Aperture Spherical Telescope (FAST) are presented: a circular stepped horn and a circular profiled horn. The optical configuration of FAST imposes requirements on the antenna design. These requirements are used in optimizing the horn designs. Simulated results for the horns performance are presented and the ability of the designs to achieve FAST´s requirements is discussed.
