Abstract

A handheld device can include an encasing, one or more appurtenances associated with the encasing, communications circuitry contained within the encasing, and antenna elements. The antenna elements can be electrically coupled to the communications circuitry and integrated with the encasing and the one or more appurtenances. The appurtenances can include any of a touch-sensitive display screen, a button, a joystick, a click wheel, a scrolling wheel, a touchpad, a keypad, a keyboard, a microphone, a speaker, a camera, a sensor, a light-emitting diode, a data port, or a power port.

First claim

The invention claimed is:

1. A handheld device, comprising:
an encasing including electrically conductive material;
one or more appurtenances including any of a touch-sensitive display screen, a button, a joystick, a click wheel, a scroll wheel, a touchpad, a keypad, a camera, a data port, or a power port forming part of the encasing, the one or more appurtenances including electrically conductive material;
communications circuitry contained within the encasing and operable to process communications signals; and
a plurality of antenna elements electrically coupled to the communications circuitry and formed of (a) the electrically conductive material of the encasing and (b) the electrically conductive material of the one or more appurtenances such that the encasing and the one or more appurtenances are separated by a non-conductive irregularly shaped antenna break and are operable as an antenna of the handheld device to wirelessly communicate radio signals capable of being processed by the communications circuitry.

2. The handheld device of claim 1 , wherein the irregularly shaped antenna break is non-linear along a single plane.

3. The handheld device of claim 1 , wherein the irregularly shaped antenna break has a variable width.

4. The handheld device of claim 1 , wherein the irregularly shaped antenna break separates at least one of the plurality of antenna elements integrated with the encasing and at least one of the plurality of antenna elements integrated with at least one of the one or more appurtenances.

5. The handheld device of claim 4 , wherein the at least one of the one or more appurtenances comprises a camera including a bezel and a lens, the bezel holding the lens to the encasing.

6. The handheld device of claim 5 , wherein the bezel comprises the at least one of the plurality of antenna elements integrated with the camera.

7. The handheld device of claim 6 , wherein the irregularly shaped antenna break surrounds the bezel to separate the at least one of the plurality of antenna elements integrated with the camera and the at least one of the plurality of antenna elements integrated with the encasing.

8. The handheld device of claim 1 , wherein at least some of the plurality of antenna elements integrated with the encasing are separated by at least one concealed antenna break.

9. The handheld device of claim 8 , wherein the encasing comprises:
a continuous layer of non-conductive material, the continuous layer forming an exterior surface of the encasing; and
a contiguous layer of conductive regions separated by at least one non-conductive region, the contiguous layer forming an interior surface of the encasing, and the conductive regions correspond to the at least some of the plurality of antenna elements and the at least one non-conductive region corresponds to the at least one concealed antenna break.

10. The handheld device of claim 1 , wherein the one or more appurtenances comprises a touch-sensitive display screen including driving lines and sensing lines to receive touch input, and at least some of the plurality of antenna elements are integrated with at least one of the driving lines or sensing lines.

11. The handheld device of claim 1 , wherein the one or more appurtenances comprises a display screen including a plurality of conductive elements configured to enable rendering images on the display screen, and at least some of the plurality of antenna elements correspond to the plurality of conductive elements configured to enable rendering images on the display screen.

12. The handheld device of claim 1 , wherein at least some of the plurality of antenna elements are automatically disabled while other antenna elements of the plurality of antenna elements are enabled.
