A radio frequency identification tag device includes an antenna unit (1) including a dielectric substrate (11) that has two through holes (113) extending from a first surface (111) to a second surface (112) opposite to the first surface (111), a first conductive layer (12) disposed over the first surface (111) of the dielectric substrate (11), a second conductive layer unit (13) disposed over the second surface (112) of the dielectric substrate (11) and having opposite second conductive layers (131, 132) spaced apart from each other such that a spacer (130) is formed between the second conductive layers (131, 132), and two connecting conductors (14) each disposed in a corresponding through hole (113) in the dielectric substrate (11) and interconnecting electrically a corresponding second conductive layer (131, 132) and the first conductive layer (12). A radio frequency identification module (2) is disposed to span the spacer (130) and is attached to the second conductive layer unit (13). |
