Title:
ANTENNA DEVICE AND WIRELESS DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/035821
Kind Code:
A1
Abstract:
This RFID tag (401) is provided with an antenna element (101) and a feeder device (301). The antenna element (101) is configured from a substrate sheet (10) and a coil conductor (11) formed on the upper surface thereof. The feeder device (301) is configured from a feeder element (201) and an RFIC (30). The feeder element (201) is configured from a substrate sheet (20), and a first coil conductor (21) and second coil conductor (22) formed on the upper surface of the substrate sheet (20). The first coil conductor (21) and the second coil conductor (22) are formed to the substrate sheet (20) in a manner so that the magnetic flux arising at the first coil conductor (21) and the second coil conductor (22) configures a closed magnetic circuit. Also, the feeder device (301) is pasted to the joining section (CA) of the antenna element (101). As a result, the RFIC is strongly joined to the antenna element.
