<RFIC element>
FIG. 2A is a cross-sectional view of the RFIC element 2 of the shoe RFID tag 20 according to the first embodiment. FIG. 2B is an equivalent circuit diagram of the RFIC element 2 of FIG.
The RFIC element 2 includes an RFIC chip 21 and a multilayer substrate 25 connected to the RFIC chip 21 via a conductive bonding material 22 and a terminal electrode 23. The multilayer substrate 25 may be, for example, a flexible element. The RFIC chip 21 is sealed with a sealing resin 24. In addition, the multilayer substrate 25 has a built-in power supply circuit including an L pattern such as L1 and L2 and a C pattern such as C1 and C2. C _IC is a stray capacitance of the RFIC chip 21. A resonance circuit is formed by the power feeding circuit, and the resonance frequency corresponds to the carrier frequency. By providing the feeding circuit in this way, the center frequency of the carrier frequency can be prevented from changing greatly even if the electrical length of the antenna pattern 10 changes.
In other words, if the electrical length of the antenna pattern 10 in the initial state is matched with the maximum gain state (2 / λ), even if the electrical length of the antenna pattern 10 slightly changes, the communicable distance only decreases, and the same carrier Reading by frequency is possible.

  The RFIC element 2 and the first and second connection patterns 4a and 4b constituting the antenna pattern 10 may be directly connected by, for example, terminal electrodes 26a and 26b. In this case, the terminal electrode 26a and the first connection pattern 4a are connected, and the terminal electrode 26b and the second connection pattern 4b are connected. Further, the RFIC element 2 and the first and second connection patterns 4a and 4b may be coupled not only directly by the terminal electrodes 26a and 26b but also by any coupling such as capacitive coupling and magnetic field coupling.

In FIG. 2, the RFIC element 2 is provided with the multilayer substrate 25 in which the power feeding circuit is built.
As a carrier frequency of the RFID tag for shoes, for example, a 13 MHz band in the HF band RFID system, a 900 MHz band in the UHF band RFID system, or the like can be used. In particular, since the UHF band RFID system has a relatively long communication distance, it can collectively read a plurality of RFID tags 20 for shoes.

Specifically, the closure portions 5a and 5b have a thin plate shape having openings 6a and 6b that lack a part of the periphery. In other words, the openings 6a and 6b have notches 7a and 7b on the periphery. The notches 7a and 7b may not have a gap. The shoe RFID tag 20 is attached to the shoe by passing the shoelace of the shoe through the openings 6a and 6b through the notches 7a and 7b on the periphery of the openings 6a and 6b of the closure portions 5a and 5b. The closure portions 5a and 5b may have protrusions (returns) toward the inside of the opening at the peripheral edges on both sides of the notches 7a and 7b. The protrusions (returns) 8a and 8b can prevent the shoelaces that have entered the openings 6a and 6b from being detached (detached) through the notches 7a and 7b.

  The closure portions 5a and 5b are provided at the ends of the base material 1, that is, at both ends in the longitudinal direction of the base material 1 in the case of FIG. Further, the closure portions 5 a and 5 b are harder than the base material 1.

The closure parts 5a and 5b may be made of, for example, polystyrene. Moreover, it should just be harder than the base material 1, and may consist of another material.
The closure parts 5a and 5b may include a member called a detachable part.

<Label>
The shoe RFID tag 20 may have a label attached to the upper surface of the antenna pattern 10 of the substrate 1 as necessary. For example, the name of the tournament to be used may be attached to the label. The antenna pattern can be protected by the label.
