Abstract

An integrated circuit for use in an RFID tag includes an integrated circuit die having a circuit, a radio frequency identification (RFID) interface for providing communication between the circuit and a remote RFID reader via RF signaling between the RFID interface and the remote RFID reader, and an antenna section for facilitating the RF signaling between the RFID and the remote RFID reader. A substrate is coupled to support the first integrated circuit die.

Claims (38)

1. An integrated circuit for use in an RFID tag, the integrated circuit comprising:

an integrated circuit die including:

a circuit that generates first data;

a radio frequency identification (RFID) interface, coupled to the circuit, for providing communication between the circuit and a remote RFID reader via RF signaling between the RFID interface and the remote RFID reader, wherein the RF signaling between the RFID interface and the remote RFID reader includes millimeter wave RF signals that carry the first data in a V-band range of frequencies;

an antenna section, coupled to the RFID interface, for facilitating the RF signaling between the RFID and the remote RFID reader;

a substrate coupled to support the first integrated circuit die.

2. The integrated circuit of claim 1 wherein the RF signaling between the RFID interface and the remote RFID reader includes reception of a millimeter wave RFID signal from the remote RFID reader and the backscattering of the millimeter wave RFID signal by the RFID interface.

3. The integrated circuit of claim 1 wherein the antenna section includes at least one bonding wire that connects the integrated circuit die to couplers for electrically connecting the integrated circuit to at least one external device and further operates as at least a portion of an antenna.

4. The integrated circuit of claim 3 wherein the at least one bonding wire includes:

a first bonding wire that couples first signals between the circuit and the substrate; and

a second bonding wire that couples second signals between the circuit and the substrate.

5. The integrated circuit of claim 3 wherein the at least one bonding wire further provides impedance matching to the RFID interface and the antenna section.

6. The integrated circuit of claim 3 wherein the at least one bonding wire further provides a transmission line.

7. The integrated circuit of claim 1 wherein the antenna section includes at least one power supply line for coupling power to the integrated circuit from a direct current power source and that further operates as at least a portion of an antenna.

8. The integrated circuit of claim 7 wherein the at least one power supply line includes:

a first power supply line for coupling a power signal to the circuit; and

a second power supply line for coupling the power signal to the circuit.

9. The integrated circuit of claim 8 wherein the at least one power supply line further provides impedance matching to the RFID interface and the antenna section.

10. The integrated circuit of claim 8 wherein the at least one power supply line further provides a transmission line.

11. An integrated circuit for use in an RFID tag, the integrated circuit comprising:

an integrated circuit die including:

a circuit;

a radio frequency identification (RFID) interface, coupled to the circuit, for providing communication between the circuit and a remote RFID reader via RF signaling between the RFID interface and the remote RFID reader in a V-band range of frequencies;

an antenna section, coupled to the RFID interface, for facilitating the RF signaling between the RFID and the remote RFID reader;

a substrate coupled to support the first integrated circuit die.

12. The integrated circuit of claim 11 wherein the RF signaling between the RFID interface and the remote RFID reader includes reception of a millimeter wave RFID signal from the remote RFID reader and the backscattering of the millimeter wave RFID signal by the RFID interface.

13. The integrated circuit of claim 11 wherein the antenna section includes at least one bonding wire that connects the integrated circuit die to couplers for electrically connecting the integrated circuit to at least one external device and further operates as at least a portion of an antenna.

14. The integrated circuit of claim 13 wherein the at least one bonding wire includes:

a first bonding wire that couples first signals between the circuit and the substrate; and

a second bonding wire that couples second signals between the circuit and the substrate.

15. The integrated circuit of claim 13 wherein the at least one bonding wire further provides impedance matching to the RFID interface and the antenna section.

16. The integrated circuit of claim 13 wherein the at least one bonding wire further provides a transmission line.

17. The integrated circuit of claim 11 wherein the antenna section includes at least one power supply line for coupling power to the integrated circuit from a direct current power source and that further operates as at least a portion of an antenna.

18. The integrated circuit of claim 17 wherein the at least one power supply line includes:

a first power supply line for coupling a power signal to the circuit; and

a second power supply line for coupling the power signal to the circuit.

19. The integrated circuit of claim 18 wherein the at least one power supply line further provides impedance matching to the RFID interface and the antenna section.
