<P>PROBLEM TO BE SOLVED: To provide a composite magnetic antenna which transmits and receives information using magnetic components, and a composite RF tag using the antenna, which is a type embedded in metal that is impossible for conventional RF tags and its adequate communication sensitivity is ensured. <P>SOLUTION: The composite RF tag transmits and receives information using an electromagnetic induction method, and is composed of an IC mounted magnetic antenna, an insulator formed around the magnetic antenna, and a metal or a conductor. The magnetic antenna is formed so that an electrode material is coiled around a magnetic core, the insulator is formed around the magnetic antenna excluding one end of the coil longitudinal direction, and the metal or the conductor is formed outside of the insulator. <P>COPYRIGHT: (C)2010,JPO&INPIT |
