Author:Mofolo, ROM; Lysko, Albert A; Olwal, TO; Clarke, WADate:Sep 2011In this paper, the authors present a method of electronic beam steering for circular switched parasitic array (SPA) antennas. In circular SPA antennas, one achieves azimuth beam steering by open-circuiting and short-circuiting different ...Read more
Author:Mofolo, M; Lysko, Albert A; Clarke, WDate:Sep 2010This paper presents a method of electronic beam steering for a smart antenna system based on a switched parasitic array. The antenna system is made up of circular array of half wave dipoles, with four parasitic elements positioned equidistantly, ...Read more
