Abstract

A radio frequency identification (RFID) tag includes a base supporting an integrated circuit and a first antenna orthogonal to a second antenna, the first antenna and the second antenna coupled to the integrated circuit, and a first fold in the base that when creased, defines two lobes lying in two planes, a first lobe including a first portion of the first antenna positioned in an x-axis relative to the second antenna oriented along a y-axis, and a second lobe including a second portion of the first antenna positioned in a z-axis relative to the first portion of the first antenna and second antenna.

Claims

1. A radio frequency identification (RFID) tag comprising:

a base supporting an integrated circuit and a first antenna orthogonal to a second antenna, the first antenna and the second antenna coupled to the integrated circuit; and

a first fold in the base that when creased, defines two lobes lying in two planes, a first lobe including a first portion of the first antenna positioned in an x-axis relative to the second antenna oriented along a y-axis, and a second lobe including a second portion of the first antenna positioned in a z-axis relative to the first portion of the first antenna and second antenna.

2. The RFID tag of claim 1 wherein the first lobe includes a first conductor on an end of the first portion of the first antenna and the second lobe includes a second conductor on an end of the second portion of the first antenna, the first conductor and the second conductor making electrical contact at an intersection along the first fold when creased.

3. The RFID tag of claim 1 wherein the first fold comprises perforations.

4. The RFID tag of claim 1 wherein the base is L-shaped.

5. The RFID tag of claim 4 wherein the flexible portion further comprises:

a third antenna coupled to the integrated circuit and orthogonal to the first antenna and the second antenna; and

a second fold that when creased, defines a third lobe lying in a parallel plane and including a portion of the third antenna.

6. The RFID tag of claim 5 wherein the second fold comprises perforations.

7. A radio frequency identification (RFID) tag comprising:

an L-shaped base an integrated circuit and a first antenna orthogonal to a second antenna and a third antenna orthogonal to the first antenna and the second antenna, the first antenna, the second antenna and the third antenna coupled to the integrated circuit;

a first fold in the flexible portion that when creased, defines two lobes lying in two planes, a first lobe including a first portion of the first antenna positioned in an x-axis relative to the second antenna oriented along a y-axis, and a second lobe including a second portion of the first antenna positioned in a z-axis relative to the first portion of the first antenna and second antenna; and

a second fold in the flexible portion that when creased, defines a third lobe lying in a parallel plane to the first lobe and including a portion of the third antenna.

8. The RFID tag of claim 7 wherein the first fold and the second fold comprise perforations.

9. The RFID tag of claim 7 wherein the first fold and the second fold comprise creases.

10. A radio frequency identification (RFID) tag comprising:

a flexible base comprising two perpendicular folds and supporting on a first side an integrated circuit and a first portion of an antenna, the first portion of the antenna including a conductor on an end;

a second portion of the antenna positioned on a second side of the base and including a conductor on an end;

the conductor on the first portion of the antenna and the conductor on the second portion of the antenna making electrical contact at an intersection along one of the folds when creased.

11. The RFID tag of claim 10 wherein the first fold and the second fold comprise perforations.

12. The RFID tag of claim 10 wherein the first fold and the second fold comprise creases.

14. A radio frequency identification (RFID) device comprising:

a L-shaped base including a first and second fold, the first and second folds defining three regions of the base;

an integrated circuit positioned on a first region of the base;

a first lead and a second lead coupled to the integrated circuit and lying in the first region and a second region of the base, the first lead and the second lead each terminated with a conductor; and

a first antenna and a second antenna lying in a third region of the base, the first and second antennas positioned orthogonal to each other and each terminated with a conductor, the conductor on the first lead and the conductor on the first antenna making electrical contact at an intersection along the first fold when the first and second folds are creased, the conductor on the second lead and the conductor on the second antenna making electrical contact at the intersection along the first fold when the first and second folds are creased.

15. The RFID tag of claim 14 wherein the first fold and the second fold comprise perforations.

16. The RFID tag of claim 14 wherein the first fold and the second fold comprise creases.
