Abstract

Methods and apparatus applying RFID technology to identify electronic components, devices, and systems to provide functions such as, for example, security of the assets, inventory tracking of the assets, identification of the assets, and short distance communication between the assets are disclosed. RFID transponders are integrated into electronic components, devices and systems at the component level (i.e., circuit chip, circuit board, etc.), the asset level (i.e., box, computer, etc.), or system level (i.e., network system, computer system, etc.).

Claims

1. An electronic component having an integrated RF transponder for communicating information about the component to an RFID system, said electronic component comprising:

a substrate;

a plurality of packaged integrated circuits each configured to provide a function of the electronic component wherein at least two of said packaged integrated circuits include an RF transponder circuit, said RF transponder circuit containing memory for storing information about the electronic component and an RF transmitter and receiver section for communicating the information to the RFID system.

2. The electronic component of claim 1, further comprising at least two antennas formed on said substrate, wherein each antenna is coupled to a different RF transponder circuit.

3. The electronic component of claim 1, further comprising a single antenna coupled to each of the at least two RF transponder circuits so that the antenna is shared.

4. An electronic device capable of communicating information to an RFID system, said electronic device comprising:

an electronic component configured to provide a function of the electronic device, the electronic component further comprising a printed circuit board including a substrate; and

an RF transponder mounted to said substrate within the electronic device, said RF transponder including an RF transmitter and receiver section for communicating the information to the RFID system, said RF transponder further including an antenna formed on the substrate; and

a dual antenna assembly including an internal antenna mounted within the housing and an external antenna mounted outside the housing, the internal antenna coupled to the external antenna for conveying RF signals between said RF transponder and the RFID system.

5. An electronic device capable of communicating information to an RFID system, said electronic device comprising:

an electronic component configured to provide a function of the electronic device;

a housing enclosing said electronic component;

an RF transponder mounted within the electronic device, said RF transponder including an RF transmitter and receiver section for communicating the information to the RFID system, and

wherein the electronic component comprises a printed circuit board including a substrate and wherein at least part of the RF transponder is mounted to the substrate, and wherein the RF transponder includes a radio frequency identification integrated circuit (RFID IC) comprising a signal processing section mounted to the substrate and an RF front end mounted on the housing and coupled to an antenna.

6. The electronic device of claim 5, wherein the antenna is mounted to the housing.

7. The electronic device of claim 5, wherein the antenna is an externally provided antenna.
