heal.abstract	A new technique for the design of broadband circular switched parasitic arrays (SPAs) for portable DVB-T receiver applications in the VHF/UHF bands is presented in this paper. Two swithed parasitic arrays are presented, consisting of an active central element and uniform ring of five parasitic elements. Ar any given time slot, only one parasitic element is open-circuited, while the rest remain short-circuited. By properly selecting the open-circuited element, the array is able of selecting among five horizontal radiation patterns. These cover the horizontal plane in a uniform manner, thus achieving effective beam steering in order to maximize and minimize the received power and bit error rate, respectively. Measurement results for both arrays and for a single switching state are presented, and exellent agreement with design considerations and numerical results is demonstrated. © 2008 IEEE.	en
