Abstract :
A Rotman type lens using a hyperbolic focal arc has been proposed. The proposed lens has been analysed using the contour integral technique. The results obtained for the proposed lens have been compared with the result obtained for the Rotman lens. It has been found that by using the hyperbolic focal arc, a wide area can be scanned
