Abstract

This invention provides a wide band IC tag in which the vicinity of an IC portion arranged in a tag main body can be arranged in a portion difficult to be influenced by an object. Therefore, this invention is characterized in the wide band IC tag for connecting the IC portion arranged in the tag main body and an antenna portion, wherein the IC portion is arranged at an end of the tag main body.

Claims

1. A wide band IC tag for connecting an IC portion arranged in a tag main body and an antenna portion, and functioning in a frequency band from a UHF band to an SHF band;

wherein said IC portion is arranged at an end of said tag main body.

2. The wide band IC tag according to claim 1, wherein the end of said tag main body is constructed by an edge portion or an angular corner portion of the tag main body.

3. The wide band IC tag according to claim 1 or 2, wherein said antenna portion is constructed by an antenna element of a loop shape.

4. The wide band IC tag according to claim 1, wherein said antenna portion is constructed by plural antenna elements of different element lengths.

5. The wide band IC tag according to claim 4, wherein said antenna element is arranged in a comb shape or a fan shape.

6. The wide band IC tag according to claim 3, wherein an arbitrary portion of said antenna element is bent.

7. The wide band IC tag according to claim 3, wherein the number of said antenna elements is set to an arbitrary number.

8. The wide band IC tag according to claim 3, wherein the entire length or one portion of said antenna element is formed in a curve structure.
