Radio frequency identification tag device for metallic products |
摘要 |
A radio frequency identification tag device includes an antenna unit including a dielectric substrate that has two through holes extending from a first surface to a second surface opposite to the first surface, a first conductive layer disposed over the first surface of the dielectric substrate, a second conductive layer unit disposed over the second surface of the dielectric substrate and having opposite second conductive layers spaced apart from each other such that a spacer is formed between the second conductive layers, and two connecting conductors each disposed in a corresponding through hole in the dielectric substrate and interconnecting electrically a corresponding second conductive layer and the first conductive layer. A radio frequency identification module is disposed to span the spacer and is attached to the second conductive layer unit. |
