A universal IC tag comprises a metal sheet M 1 having a hollow slot functioning as an antenna; plastic sheets laminated on the front and the rear surfaces of the metal sheet M 1 ; an IC arranged in the hollow slot, and a metal sheet M 2 laminated on the rear plastic sheet having a reflecting amplifying function. Such universal IC tag can transmits/receive maximum energy by matching IC impedance with slot impedance and by attaining resonance between an IC capacitor and a slot inductance. |
