Radio communication tag and method for manufacturing the same
First Claim
1. A radio communication tag comprising:
- a flexible base sheet;
an antenna conductor provided on the base sheet;
a reinforcing layer provided on a first main surface of the base sheet; and
an RFIC element mounted on a second main surface of the base sheet, the RFIC element including a connection terminal connected to the antenna conductor;
whereinthe RFIC element is surrounded by a contour of the reinforcing layer in a plan view,the connection terminal is exposed on the second main surface of the base sheet,the antenna conductor includes a loop pattern surrounding the RFIC element in the plan view, andthe contour of the reinforcing layer is surrounded by the loop pattern in the plan view.

Abstract
An antenna conductor and a reinforcing layer are provided on an upper surface and a lower surface, respectively, of a flexible base film. An RFIC element is mounted on the upper surface of the base film. Two I/O terminals provided on the RFIC element are each connected to meander patterns of the antenna conductor. In a plan view, the reinforcing layer has a circular contour, and the RFIC element is surrounded by the contour of the reinforcing layer. The two I/O terminals provided on the RFIC element are exposed on the upper surface of the base film. Breakage of the connected portion between the RFIC element and the antenna conductor is prevented, and any breakage that has occurred is easily identified.
