Title:
RFID TAG DEVICE FOR STEEL PRODUCT
Document Type and Number:
WIPO Patent Application WO/2014/200196
Kind Code:
A1
Abstract:
The present invention provides an RFID tag device for a steel product. When an RFID tag attached to a steel product is placed in various external environments depending on stacking and moving of steel products, and particularly is placed in a stacked structure where the RFID tag is drawn out of a stack of steel plates or is sandwiched between upper and lower steel plates, the present invention overcomes the problem of recognition impossibility in various stacking conditions, in which an internal field may be excited in the stacked structure, and enables stable transmission/reception , in consideration of the propagation characteristics of the stacked structure.
