Abstract
An enhanced portable communication device includes a one-piece metal back plate, configured to reduce device thickness by eliminating the plastic-to-metal joints normally needed to isolate the device antennas and provide rigidity. The one-piece metal back plate includes four integral antennas in an embodiment, forming an antenna pair at each end of the device. An opening and gap used to form each antenna pair may be filled with a nonconductive material such as plastic. In an embodiment, an I/O port is exposed through the nonconductive material in the gap.
Claims9
A portable electronic device housing comprising:
- a single-piece conductor having a main body, a periphery and having two antenna arms formed in the periphery, each antenna arm comprising a strip of the conductor electrically connected to the remainder of the main body of the conductor at one end the two antenna arms together partially enclose an opening in the main body, the opening being in the plane of the main body of the back plate;
- a non-conductive material positioned to fill the opening in the;
- and
- a camera and flash extending through the non-conductive material, the camera and flash being electrically isolated from the single-piece conductor.
