Abstract

The invention relates to a wireless communication device that is coupled to an energy source, such as a battery, capacitor, or solar cell. The wireless communication device is coupled to an antenna of the energy source for wireless communication. The antenna receives communication signals from an interrogation reader or other communication device. The wireless communication device may be attached to a device or container for purposes such as communicating information regarding identification, manufacturing, tracking, and the like. The wireless communication device may also be coupled to the energy source for power.

Claims

1. A wireless communication energy source system, comprising:

an energy source comprising a body having a first and a second terminal separated by a separator between said first and second terminals to form an antenna for wireless communication; and

a wireless communication device coupled to said antenna;

wherein said wireless communication device is coupled to said antenna using at least one feed point; and

wherein said wireless communication device is coupled to said first and second terminals to provide power to the wireless communication device.

2. The system of claim 1, wherein said wireless communication device is coupled to said first terminal using a feed line and said wireless communication device is directly coupled to said second terminal through a conductive portion of said wireless communication device.

3. The system of claim 2, wherein said wireless communication device comprises a pin and said wireless communication device is directly coupled to said second terminal using said pin.

4. The system of claim 1, wherein said wireless communication device is coupled to said first terminal using a first feed line and said second terminal using a second feed line.

5. The system of claim 4, wherein said first feed line coupled to said first terminal comprises a conductive adhesive and said second feed line coupled to said second terminal comprises a conductive adhesive.

6. The system of claim 5, wherein said first feed line further comprises a portion of non-conductive adhesive, said conductive adhesive portion of said first feed line coupled to said first terminal and said non-conductive adhesive portion of said first feed line coupled to said second terminal.

7. The system of claim 1, wherein said wireless communication device is coupled to said antenna using a first of said at least one feed point, said first feed point comprising a conductive adhesive.

8. The system of claim 1, further comprising an interrogator configured to communicate information wirelessly with said wireless communication device.

9. The system of claim 8, wherein said interrogator emits a signal to said wireless communication device to power said wireless communication device.

10. The system of claim 9, wherein said signal recharges said energy source.

11. The system of claim 9, wherein said interrogator communicates to said wireless communication device to transfer information.
