Abstract
A radio communications device (100) having an antenna radiator assembly (19) has radio frequency communications circuitry (2), a ground plane (40), a radio frequency radiator element (7) and connectors each physically contacting the radio frequency radiator element (7) at contact points. A feed point (30) formed by one of the connectors couples the radio frequency radiator element (7) to the radio frequency communications circuitry (2). Grounds links (32, 36a, 36b, 36c) formed the connectors selectively couple the radio frequency radiator element (7) to the ground plane (40) via a switching unit (22). When operating in a specific frequency band during a transmit mode, the switching unit (22) selects one the connectors to provide a transmit frequency sub-band, and when operating in the specific frequency band during a receive mode, the switching unit selects another of the connectors to provide a receive frequency sub-band.
