<P>PROBLEM TO BE SOLVED: To provide a noncontact IC tag label, capable of gradually adjusting the frequency according to the change of the resonance frequency, when it is attached to an article. <P>SOLUTION: In the noncontact IC tag label 1, an IC chip 3, having processing function, storage function, and an I/O control function is connected to an antenna coil 2 formed on a base film 11, and an adhesive layer for attaching articles is arranged in the opposite surface of the antenna coil 2 on the base film 11. In the noncontact IC tag label, frequency adjustment patterns 5, 6 forming a capacitor between themselves and a conductive layer of the opposite side to the base film are formed, in the outer peripheral area of the antenna coil 2. The resonance frequency of a resonance circuit can be adjusted, by adjusting the capacity of the capacitor by cutting off the frequency adjustment patters. The noncontact IC tag label 1 can also be provided with a adjustment resistive pattern for adjusting the Q-value. <P>COPYRIGHT: (C)2007,JPO&INPIT |
