Title: COMPOSITE RF TAG AND TOOL PROVIDED WITH THE COMPOSITE RF TAG
Abstract:
Provided is a composite RF tag for transmitting/receiving information using an electromagnetic induction system. The composite RF tag is composed of a magnetic material antenna having an IC mounted thereon, and a resin layer formed around the magnetic material antenna, and the magnetic material antenna is formed such that an electrode material has a coil shape with the core composed of a magnetic material at the center. In the composite magnetic material RF tag, influences of the surrounding water and metals are suppressed to be minimum for management of tools and components, and damages and breakage are eliminated by forming the magnetic antenna such that the antenna is surrounded by the resin.
