Abstract

A modified approach to design Rotman (1963) type multiple beam forming lens has been proposed. The path length error at the wavefront has been calculated. The error obtained by the proposed approach and by the conventional approach has been compared. Two-dimensional electromagnetic field analysis of the lens obtained by the modified approach and by the conventional approach lens has been carried out using the contour integral method. The results obtained for both the lenses have been compared
