Abstract

A system (115) provides enhanced radiation performance for a communication device (10). The system (115) includes one or more shields (90) for directing radio frequency energy. The one or more shields (90) are isolated from the radio frequency currents on the ground plane of the communications device (10). The system (115) further includes a display bezel (60) also isolated from the radio frequency currents on the ground plane. The system (115) further includes one or more impedance blocks electrically connected between the display bezel (60) and a printed circuit board (25) for providing a direct current ground path between the display bezel (60) and the printed circuit board (25) and for providing radio frequency isolation between the display bezel (60) and the printed circuit board (25).
