The theory behind theproposed idea is presented. The preliminary numerical re\-sults that are obtained suggest that the proposed congura\-tion is promising. It allows achieving a wide frequency bandand low dynamic range ratio of excitations, thus simplifyingthe feeding network. Further interesting requirements maybe satised by exploiting a combination of deterministic andstochastic synthesis techniques to design the array."]
