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).
Abstract:
A planar inverted-F antenna structure (204) is parasitically coupled to a conductor loop (214) at an open end (208) of the main radiator of the inverted-F antenna. The conductor loop is grounded (216).
Abstract:
A dual input mobile communication device. The mobile communication device can include a housing having an exterior, the exterior including a first face side and a second face side, the second face side located on an opposite side of the housing from the first face side, a first display disposed on the first face side, a numeric keypad disposed on the first face side, a second display disposed on the second face side, and a text keypad disposed on the second face side. The numeric keypad can be a telephone keypad such as a dual-tone multiple-frequency (DTMF) keypad and text keypad can be a QWERTY keypad, such as a keypad having a layout similar to a typical typewriter-style keyboard. The housing can be a candy bar phone style housing.
