The Analysis and Design of a Broadband Constant Beam Width Reflector Dish Atenna

University of Utah

This paper presents the design and analysis of a broadband constant beam width reflector dish antenna for use with a multi-frequency scatterometer. The scatterometer physical and electrical antenna requirements are very strict. The far-field analysis used in the design is presented. The reflector shape is discussed including a optimization technique for the reflector shape. The simulated antenna patterns before and after optimizing the reflector shape are included.
