Title:
ANTENNA CIRCUIT STRUCTURE BODY FOR IC CARD/TAG AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2011/162088
Kind Code:
A1
Abstract:
Provided are an antenna circuit structure body for an IC card/tag and a production method therefor, wherein the load applied to the environment can be reduced in a production step for jointing opposite ends of an antenna circuit pattern layer, and the reliability at the joint portions of the opposite ends of the antenna circuit pattern layer can be increased. In an antenna circuit structure body for an IC card/tag, an insulation layer (107) is formed to extend from the upper portion of a first circuit pattern layer part (103) through the upper portion of an antenna coil part (101) to the upper portion of a second circuit pattern layer part (104). A conductive layer (108) is formed on the insulation layer (107) to allow conduction between the first circuit pattern layer part (103) and the second circuit pattern layer part (104). The insulation layer (107) comprises a plurality of inclined ends on the first circuit pattern layer part (103) and the second circuit pattern layer part (104), respectively.
