US 20070200782 A1Abstract
FIG. 1A is a plan view showing the configuration of an RFID tag according to this embodiment. FIG. 1B is a bottom view showing the configuration of the RFID tag according to this embodiment. FIG. 1C is a front view showing the configuration of the RFID tag according to this embodiment. FIG. 1D is a rear view showing the configuration of the RFID tag according to this embodiment. FIG. 1E is a right side view showing the configuration of the RFID tag according to this embodiment. FIG. 1F is an enlarged view of a portion where a meandering part 13 a and a radiating part 14 a are connected in the RFID tag according to this embodiment. FIG. 1G is an enlarged view of the vicinity of a portion where a meandering part 13 b and a radiating part 14 b are connected in the RFID tag according to this embodiment. Further, since a left side view and a right side view are symmetrical, the left side view will be omitted. In the drawings, the RFID tag 100 includes an antenna 1, a dielectric substrate 2, an integrated circuit 3, and a strap 4. In addition, the antenna 1 includes power feeding parts 11, a matching circuit 12, a pair of meandering parts 13 a and 13 b, and a pair of radiating parts 14 a and 14 b. The antenna 1 is used to transmit and receive an electric wave. The antenna may be made of any material as long as the antenna is made of conductor. In general, a filmy conductor, for example, metal is used as the antenna 1. However, the thickness of the conductor is not limited. Here, the following antenna will be described. The antenna 1 is made of aluminum and has a uniform thickness of about 15 μm. Further, the antenna 1 has a length of 94 mm in the longitudinal direction and a width of 16.025 mm. However, a size of the antenna 1 can be modified depending on the band of where the antenna 1 is used. Furthermore, the antenna 1 is disposed on the rear surface of the dielectric substrate 2 in this embodiment.
