1. An RFID antenna structure for use with an RFID device, comprising;
- a conductive material having first and second portions;
the first portion having a first antenna pattern and the second portion having a second antenna pattern distinct from the first antenna pattern;
the second antenna pattern cooperates with a conductive surface; and
wherein the second portion is folded onto a section of the second portion and attached to a part of the conductive surface such that the second portion does not significantly modify performance of the first portion and the antenna structure is wrapped which effectively retunes the antenna structure.

Abstract
A radio frequency identification (“RFID”) antenna structure such as may be found on a tag, label or inlay for use with consumer products that has a conductive surface. The RFID structure of the present invention can be attached to the conductive surface without significantly modifying the performance of the RFID device. The RFID device has first and second portions, with the first portion having a first antenna pattern and the second portion including an elongate section for attachment to the consumer item.

13. An RFID device, comprising:
-
an RFID antenna structure comprising; a conductive material having first and second portions; the first portion having a first antenna pattern and the second portion having a second antenna pattern distinct from the first antenna pattern; the second antenna pattern cooperates with a conductive surface; and wherein the second portion is folded onto a section of the second portion and attached to a part of the conductive surface such that the second portion does not significantly modify performance of the first portion, and a chip and a substrate, wherein the antenna structure is applied to a surface of the substrate and the substrate is a label structure and the label structure has a fold line which runs about half way through the length of the label structure and allows the label structure to be folded over the first portion of the antenna. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
