ＲＦタグラベル
Document Type and Number:
Japanese Patent JP7176313
Kind Code:
B2
Abstract:
To manufacture an RF tag label at a low cost even when antennas to be mounted on the RF tag label using UHF band are designed individually.SOLUTION: An RF tag label 1 includes: a matching circuit 410 connected to an IC chip 42; an inlay 4 formed by mounting an antenna 41 on an inlay substrate 40, the antenna including two coupling elements 411 arranged symmetrically with respect to the matching circuit 410 and each electrically connected to the matching circuit 410; an auxiliary antenna sheet 2 with two conductive patterns 21 formed on one side by using conductive ink; and an adhesive layer 3 laminated on the surface of the auxiliary antenna sheet 2 where the two conductive patterns 21 are formed. Each of the two conductive patterns 21 overlaps one of the coupling elements 411 in one-to-one relationship via the adhesive layer 3.SELECTED DRAWING: Figure 1
