Abstract:
1. An antenna system for a wireless communications device comprising: a ground plane conductor defined at least by portions of a printed wiring board of the wireless communications device, said ground plane conductor defining a pair of longitudinal ends including an upper end having an open section positioned at an upper end of the wireless communications device during intended communications therefrom; and a PIFA-fed resonator having a ground end and a free end, with said ground end being electrically coupled to the ground plane conductor at a ground point located a distance away from said upper end of said pair of longitudinal ends, and with the resonator defining a feed point within the region between the ground point and said one longitudinal end, wherein at least a portion of the resonator between the feed point and the free end overlays the ground plane conductor and another portion of the resonator defines an open section relative to the ground plane conductor and said open section of the resonator is adjacent the open section of the ground plane conductor.
