Abstract :
This paper describes the reflector design and radiation characteristics of a dual-beam antenna which has a high cross-over level of adjacent beams and low sidelobe levels. To obtain the above objectives, the sub-reflector is enlarged in the horizontal plane and a new reflector-shaping technique is introduced. Moreover, a new tapered-dielectric horn with low VSWR values is proposed.
