INTEGRATED ANTENNA USING HOLLOWED-OUT NON-CONTACT IC CARD ANTENNA

摘要

PROBLEM TO BE SOLVED: To provide an integrated antenna using a hollowed-out non-contact IC card antenna which has an electric field communication antenna and a non-contact IC card antenna allocated in a same position and ensures excellent communication environment without obstructing communication each other.

SOLUTION: An integrated antenna comprises an electric field communication antenna 5 and a non-contact IC card antenna 2. The electric field communication antenna 5 has a stacked structure obtained by stacking a metal surface electrode 7b, a dielectric 6, and a metal surface electrode 7a in the order. The non-contact IC card antenna 2 has a cyclic structure obtained by laminating an antenna part 2a formed annularly, a board 2b and a magnetic material 2c formed annularly along the shape of the antenna part 2a. The magnetic material 2c of the non-contact IC card antenna 2 is mounted on the top face of the metal surface electrode 7a of the electric field communication antenna 5 so that the metal surface can be seen.
