## Background
PRIORITY REFERENCE TO PRIOR APPLICATION
This application claims benefit of and incorporates by reference patent application Ser. No. 60/686,623, entitled “Cell Ring,” filed on Jun. 3, 2005, by inventor Franklin F K Chen.


TECHNICAL FIELD 
This invention relates generally to electronics, and more particularly, but not exclusively, provides a ring or clasp with an embedded antenna or for covering an antenna of an electronic device, such as a mobile phone, global positioning satellite (GPS) device, personal digital assistant (PDA) or radio.
BACKGROUND 
Electronic devices, such as mobile phones, are easily lost as they are small and are often placed in pockets or purses where they are not secured or tethered. Accordingly, the devices can easily be misplaced or fall out.
One solution is to use clip-on mechanisms attached to the side of a device to couple the electronic device to a belt or other article of clothing. However, clip-on mechanisms, when integral with the device, make the device bulky.
Accordingly, a new non-bulky device is needed to enable the coupling of an electronic device to an object.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS
The following description is provided to enable any person having ordinary skill in the art to make and use the invention, and is provided in the context of a particular application and its requirements. Various modifications to the embodiments will be readily apparent to those skilled in the art, and the principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles, features and teachings disclosed herein.
FIG. 1 is a diagram illustrating an electronic device 100 having a circular ring (also referred to as a hook) 120. The device 100 comprises an electronics section 110 coupled to the ring 120. In one embodiment, the ring 120 has an articulated connection to the electronics section 110, enabling the ring 120 to rotate. The electronics section 110 can include a radio, GPS device, mobile phone, PDA or other device requiring an antenna. The antenna can be located within the electronics section 110 or integral with the ring 120 (e.g., the ring 120 may include an antenna 130 embedded therein).
The ring 120 can be located where an external antenna would normally be coupled to the electronics section 110, such as in the upper right or left hand corner of the electronics section 110. The ring 120 is approximately circular in shape with an inner diameter of about 0.5 inches to about 1 inch. In one embodiment, the ring 120 has an inner diameter large enough to loop around a bearer's index finger. The ring 120 can form an antenna or have an antenna within the ring 120. In an embodiment in which the antenna is embedded within the ring 120, the antenna can have a length equal to the circumference of the ring 120 (e.g., to form a loop antenna) or a length less than the circumference of the ring 120. The antenna is coupled to circuitry within the electronics section 110.
The ring 120 can be made from one or more materials, such as injection molded plastic, lightweight metals, and/or decorative metals, etc. to form a rigid structure. Accordingly, the ring 120 enables the device 100 to be hooked onto the bearer's clothing (such as belt loops and pockets), or straps/rings (such as those of a shoulder bag and backpacks). The device 100 also affords the bearer a more secure grip with a finger through the ring shaped structure of embodiments of the invention. The ring 120 also enables the bearer to twirl the device 100 around the bearer's finger.
FIGS. 2A and 2B are diagrams illustrating an electronic device 200 having a ring shaped clasp 210. The clasp 210 is substantially similar to the ring 120 except that the clasp 210 is spring loaded and is normally in a closed position as shown in FIG. 2A. The clasp 210 has a lever 220 that opens the clasp 210. The clasp 210 opens by the bearer's pushing the lever 220, which opens the clasp by deflecting an arm 230 that forms a portion of the clasp 210. Accordingly, this embodiment enables the bearer to open the clasp 210 to attach/detach the device 200 to/from the bearer's clothing or accessories.
The clasp 210 can be coupled to the electronics section 110 via a threaded attachment, adhesive, or other technique. In an embodiment of the invention, the clasp 210 can be manufactured with the electronics section 110 in a single piece.
