Title:

ANTENNA UNIT FOR NON-CONTACT COMMUNICATION, AND MOBILE COMMUNICATION APPARATUS COMPATIBLE WITH NON-CONTACT COMMUNICATION

Document Type and Number:

Japanese Patent JP2007166139

Kind Code:

A

Abstract:

To provide an antenna unit for a proximity non-contact communication system an antenna for proximity non-contact communication of which can be low-profiled, and which can ensure a communication distance characteristic of proximity non-contact communication even when the antenna unit is mounted on a mobile communication apparatus compatible with a non-contact communication system.

The antenna unit for the proximity non-contact communication system can be low-profiled by laminating the proximity non-contact communication system antenna and a plurality of magnetic bodies while ensuring the communication characteristic of the proximity non-contact communication.
