Abstract
A resonant circuit having a circuit coil formed on each surface of a dielectric film. Each coil has a line-width and an outer periphery in which the line-width of each circuit is 1/50 or more of the length of the outermost periphery of that circuit. Each coil has at least three complete turns, and the coils are provided on the faces of a dielectric film in such a manner that the coils are faced to each other.
Claims5
A resonant tag provided with a resonant circuit having at least two circuit coils comprised of a metal foil and each having a line-width and an outer periphery in which the line-width of each circuit is 1/50 or more of the length of the outermost periphery of that circuit, the circuit including a thermal adhesive resin providing a dielectric film having opposed faces, and each coil having at least three complete turns, the coils being provided respectively on opposed faces of the dielectric film in such a manner that the coils are faced to each other.
