Title:
ＲＦタグ構造体
Document Type and Number:
Japanese Patent JP7077796
Kind Code:
B2
Abstract:
To provide an RF tag structure that shortens the length of the RF tag label that stick out from a dielectric in which the communication performance of the RF tag label attached to the dielectric does not deteriorate significantly.SOLUTION: The RF tag structure 1 according to the present embodiment includes a dielectric plate 12 which is a plate-like member using a material with a high specific permittivity; a loop-shaped element 110 connected to the IC chip 113; and an RF tag label 10 implementing an antenna 11 of the structure having a surface-shaped coupling element 111 connected to the loop-shaped element 110 by utilizing the waveguide line 112, and the antenna 11 of the RF tag label 10 is designed such that the communication performance does not deteriorate significantly, a part of the loop-shaped element 110 is overhanging from the end of the dielectric plate 12, and all the coupling elements 111 are affixed to the dielectric plate 12 in a state that overlaps the dielectric plate 12.SELECTED DRAWING: Figure 1
