Abstract :
This paper presents a new technique producing overlapped subarrays by means of a transform feed displaced from the focal planes. The results indicate that the method avoids the focusing problem associated with conventional feeds, while producing radiation behavior that is nearly as high quality as that from the focal plane feed.
