Abstract
An RFID tag device includes an RFID tag having a directivity of maximum gain of electromagnetic waves therefrom in a specific direction and an RFID tag-supporting base supporting the RFID tag. The RFID tag-supporting base includes a first surface on which the RFID tag is attached and a second surface which is oppositely located with and is positioned not in parallel to the first surface to orient the maximum gain direction of the electromagnetic waves from the RFID tag toward a desired direction.

7. An RFID tag device comprising:
-
an RFID tag having a directivity of maximum gain of electromagnetic waves radiated therefrom in a specific direction;
an RFID tag-supporting base having a first surface on which the RFID tag is supported and a second surface which is located in parallel to the first surface so that a hollow body portion is created between the first and second surfaces; and
a reflection plate located in the hollow body portion of the RFID tag-supporting base to reflect the electromagnetic waves from the RFID tag, the reflection plate being rotatable in a direction intersecting the maximum gain direction of the electromagnetic waves from the RFID tag. - View Dependent Claims (8, 9, 10, 11)
