Abstract

Structures having an antenna incorporated therein are provided. Each structure may comprise one or more strips of flexible sheet material wrapped about an axis and secured together. The antenna may comprise an electrically conductive material secured to one or more of the strips in a pattern forming a closed loop except for a break in the loop defining a plurality of contracts for connection to an electrical device, which may be an RFID chip. The antenna may comprise a pair of spaced tracks with a connection therebetween, which may take the form of an intersection of the tracks or a connector. The antenna may extend for a substantial portion of the axial length of the tubular structure and may also extend helically around the tubular structure. Methods of manufacturing structures are also provided.

Claims

an antenna secured to one of the strips, the antenna comprising two spaced tracks of an electrically conductive material extending lengthwise along the strip and a closed connection therebetween, forming a closed loop except for a break in the loop defining a plurality of contacts for connection to an electrical device,

wherein the antenna helically extends along a substantial portion of the axial length of the tubular structure.

2. The structure of claim 1, wherein the closed connection comprises a connector extending between the two spaced tracks.

3. The structure of claim 2, wherein the two spaced tracks are parallel to one another.

4. The structure of claim 1, wherein the closed connection comprises an intersection of the two spaced tracks.

5. The structure of claim 1, wherein the antenna helically extends for at least one full revolution about the tubular structure.

6. The structure of claim 1, wherein the strips are wrapped one upon another about the axis, and the antenna is disposed between two adjacent strips.

7. The structure of claim 1, wherein the substantial portion is in a range of 25% to 100% of the axial length.

8. The structure of claim 1, wherein the electrically conductive material comprises a waste trim.

9. A structure having an antenna incorporated therein, comprising:

one or more strips of flexible sheet material wrapped about an axis and secured together to form a tubular structure;

an antenna secured to one of the strips, the antenna comprising an electrically conductive material arranged on the strip in a pattern forming a closed loop except for a break in the loop defining a plurality of contacts for connection to an electrical device,

wherein the antenna extends helically along the tubular structure; and

an integrated circuit device connected to the contacts.

10. The structure of claim 9, wherein the pattern comprises two spaced tracks of the electrically conductive material and a closed connection therebetween.

11. The structure of claim 10, wherein the closed connection comprises a connector extending between the two spaced tracks.

12. The structure of claim 11, wherein the two spaced tracks are parallel to one another.

13. The structure of claim 10, wherein the closed connection comprises an intersection of the two spaced tracks.
