Abstract

An antenna assembly for a radio transmitting device (10) includes a radiation absorber (80) defining an open curved shape in cross section, so as to define an open transmission area. A driven antenna (40) is disposed adjacent to the open transmission area so that during use some of the radiation emitted from the antenna (40) is absorbed by the radiation absorber (80). At least one parasitic radiation redirection element (322) receives radiation emitted from the antenna (40). The parasitic radiation redirection element (322) directs a portion of the radio signal toward the open transmission area, so as to extend a transmission of the radio signal transmitting device (10).
