Document Type and Number:
WIPO Patent Application WO/2019/064964
Kind Code:
A1
Abstract:
The present invention improves the communication characteristics of an inlay using an auxiliary antenna, while protecting the inlay from physical and mechanical external forces, shocks, or the like, without being subjected to the constraints of a dipole antenna. To that end, the present invention has a configuration comprising: an inlay 10 comprising an IC chip 11 and only a loop circuit antenna 12, on which the IC chip 11 is mounted, and not comprising another antenna; a casing 50 for accommodating the inlay 10 therein; and a planar top cover 20 covering one surface side of the casing 50. The top cover 20 is formed of a prescribed metallic material and comprises a notch 21 opening at least on one side. The inlay 10 is disposed within the casing 50 so as to be positioned inside the notch 21. The top cover 20 functions as an antenna of the inlay 10 by being electrically connected to the inlay 10.
