Abstract

A mobile device with a multi-functional external antenna comprises a housing and an external antenna. The external antenna is disposed at least partially on the housing and conforms to the housing. The external antenna is configured to one of receive wireless data signals and transmit wireless data signals. The external antenna is further configured to conduct power signals.

Claims

1. A mobile device, comprising:

a housing; and

an external antenna disposed at least partially on the housing, the external antenna conforming to the housing, the external antenna configured to one of receive wireless data signals and transmit wireless data signals, the external antenna being further configured to conduct power signals.

2. The mobile device of claim 1, further comprising:

a circuit electrically coupled to the external antenna, wherein the power signals include data, the data being transmitted to a processor of the mobile device via the circuit.

3. The mobile device of claim 2, wherein the circuit includes at least one comparator, at least one voltage clamp and a series resistance.

4. The mobile device of claim 3, wherein the external antenna is a single wire pair.

5. The mobile device of claim 4, wherein the circuit includes a full wave diode bridge allowing a polarity of the single wire pair to be reversed.

6. The mobile device of claim 5, further comprising:

a detector detecting the polarity.

7. The mobile device of claim 5, wherein the circuit further comprises four field-effect transistors reducing a voltage across the bridge.

8. The mobile device of claim 1, wherein the external antenna couples to contacts of a charging accessory to receive the power signals to charge a battery of the mobile device.

9. The mobile device of claim 1, wherein the wireless data signals one of connect to a network, perform a radio frequency identification application, and perform a positioning application.

10. The mobile device of claim 1, wherein the external antenna is a wearing plate disposed in a location of heavy wear of the mobile device.

11. The mobile device of claim 1, wherein the mobile device is received by a wearable mount.

12. The mobile device of claim 11, wherein the wearable mount is worn on at least one of a finger, a wrist, and a waist.

13. The mobile device of claim 11, wherein the external antenna couples to a connection pad of the wearable mount.

14. The mobile device of claim 13, wherein the external antenna provides the power signals to the mount via the connection pad.

15. The mobile device of claim 1, wherein the external antenna is disposed on the housing by being one of insert molded, inserted mechanically during manufacture, heat staked, adhered, transfer taped, plated directly to the housing, and a combination thereof.

16. A mount, comprising:

a dock receiving a mobile device; and

a connection pad coupling to an external antenna of the mobile device, the coupling being used for transmission of data and power signals between the mount and the mobile device.

17. The mount of claim 16, further comprising:

a full wave diode bridge circuit allowing the mount to receive the data and power signals having any polarity.

18. The mount of claim 17, further comprising:

a circuit detecting the polarity of the data and power signals.

19. The mount of claim 17, wherein the full wave diode bridge circuit includes four field effect transistors.

20. The mount of claim 16, further comprising:

a data input arrangement.

21. The mount of claim 20, wherein the data signals transmitted from the mount to the mobile device includes a status of the data input arrangement.

22. The mount of claim 20, wherein the data input arrangement is powered by the power signals received from the mobile device.

23. The mount of claim 16, further comprising:

a wearing mechanism to affix the mount to a body location, the wearing mechanism being one of straps, a ring, and a clip.

24. A mobile device, comprising:

a housing; and

a transmitting means for receiving one of wireless data signals and transmitting wireless data signals, the transmitting means further configured for receiving power signals, the transmitting means being disposed at least partially on the housing, the transmitting means conforming to the housing.

25. A mount, comprising:

a receiving means for receiving a mobile device; and

a connecting means for coupling to a transmission means of the mobile device, the connecting means being used for transmission of data and power signals between the mount and the mobile device.
