Abstract
An IC (Integrated Circuit) tag communication apparatus is capable of transporting a medium with an IC tag along a transportation path and communicating with the IC tag. The IC tag communication apparatus includes an antenna portion for communicating with the IC tag. Further, the transportation path includes a low dielectric region arranged to face the antenna portion.
Claims9
An IC (Integrated Circuit) tag communication apparatus that communicates with an IC tag, comprising:
- an antenna portion for communicating with the IC tag;
- a transportation path for transporting a medium with the IC tag embedded therein;
- a first high dielectric region;
- a low dielectric region disposed adjacent to the first high dielectric region in a transportation direction of the medium and arranged to face the antenna portion so that the medium is transported between the low dielectric region and the antenna portion;
- and
- a second high dielectric region disposed adjacent to the low dielectric region in the transportation direction of the medium.
