Abstract

A tunable radio frequency identification device and a method for customizing a radio frequency identification device are disclosed. The method for customizing the radio frequency identification device includes: providing a radio frequency identification device having a tunable antenna; and modifying the tunable antenna. As a result of modifying the antenna the inlay is tuned to operate within one of several frequencies bands.

Claims

1. A method of customizing a radio frequency identification device, the method comprising:

providing a radio frequency identification device having a tunable antenna; and

modifying the tunable antenna thereby tuning the antenna to a selected frequency, where the selected frequency is within one of a plurality of different frequency bands.

2. The method of claim 1, wherein modifying the tunable antenna includes removing one or more portions of the antenna.

3. The method of claim 2 wherein the one or more portions of the tunable antenna is removed according to a pattern.

4. the method of claim 3, wherein the pattern is selected from a plurality of patterns, wherein the selected pattern corresponds to one of the plurality of different frequency bands.

5. The method of claim 3, wherein modifying the tunable antenna further includes cutting the pattern into the antenna.

6. The method of claim 1, wherein modifying the tunable antenna includes altering the mass and shape of the tunable antenna.

7. The method of claim 6, wherein altering the mass and shape of the antenna further includes electronically connecting conductive material to the antenna.

8. The method of claim 6, wherein altering the mass and shape of the antenna further includes removing a portion of the tunable antenna.

9. A method of adjusting the resonant frequency of a radio-frequency device so that the radio-frequency device operates in one of a plurality of different frequency bands, the method comprising:

providing an inlay having an antenna disposed in a first antenna pattern;

modifying the first antenna pattern to a second antenna pattern, thereby tuning the inlay to operate at a selected frequency; and

wherein the selected frequency is within one of a plurality of different frequency bands.

10. A method according to claim 9, wherein the first antenna pattern is configured to tune the antenna to an original frequency, where in the original frequency is with in one of the plurality of different frequency bands.

11. A method of modifying an RFID inlay, the method comprising:

providing an inlay having a tunable antenna configured in a first pattern;

selecting a second pattern; and

removing a portion of tunable antenna according to the second pattern, thereby tuning the antenna to a selected frequency, where the selected frequency is within one of a plurality of different frequency bands.

12. A radio frequency device comprising:

a substrate; and

an tunable antenna disposed on the substrate and configured in a first pattern, wherein the first pattern is modifiable into a second pattern.

13. The radio frequency device according to claim 12, further comprising an integrated circuit electronically coupled to the antenna.

14. The radio frequency device according to claim 12 wherein the antenna is operable within a first frequency band when configured in the first pattern and is operable within a second frequency band when configured in the second pattern.

15. The radio frequency device according to claim 12, wherein the first pattern is modifiable into a second pattern by removing a portion of the antenna.

16. The radio frequency device according to claim 12, wherein the first pattern is modifiable into a second pattern by adding conductive material to the antenna.

17. The radio frequency device according to claim 12, wherein break-away lines are pre-cut into the antenna of the inlay according to the second patter;

and wherein the first pattern is selectably modifiable into the second pattern by removing a portion of the antenna along the break-away lines.
