Phase error at the wave-front has been calculated and it has been compared with the error obtained for the Rotman lens. Proposed elliptical refocused lens has been analyzed using the contour integral technique. Comparison of results obtained for the proposed refocused lens with those obtained for the Rotman lens indicate that lens obtained with elliptical focal arc is more compact. Copyright © SBMO.
