Title:
ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/131683
Kind Code:
A1
Abstract:
Provided is an antenna device that is thinner overall while maintaining the communication characteristics thereof. Said antenna device comprises an antenna substrate (11), an insulating layer (112) of which has an antenna coil (11a) mounted to a surface thereof, and a magnetic sheet (12) that is bonded by an adhesive layer (13) to a surface (112a) of the insulating layer (112) of the antenna substrate (11) to which the antenna coil (11a) is not mounted. The antenna coil receives a magnetic field emitted from a reader-writer (2) and is inductively-coupled to the reader-writer (2), being capable of communication therewith. The magnetic field emitted from the reader-writer (2) is drawn into the antenna coil (11a) by the magnetic sheet (12).
