- an electronic tag includes a non-contact IC tag including an IC chip having individual identification information and a transmission / reception antenna, and a magnetic tag, and the non-contact The type IC tag and the magnetic tag are overlapped at least partially via an insulating layer.
- the magnetic portion of the magnetic tag has electrical conductivity equivalent to a radio frequency used for the non-contact IC tag.
- a transmission / reception antenna of the non-contact IC tag is made of a non-magnetic material.
- the transmission / reception antenna of the non-contact type IC tag includes aluminum or copper.
- At least an impedance matching circuit portion of the non-contact IC tag does not overlap with a magnetic portion of the magnetic tag.
- the length of the magnetic portion of the magnetic tag is the non-contact type.

- Fig. 1 is a plan view showing an example of the form of the electronic tag of the present invention
- Fig. 1 (b) is a cross-sectional view showing an example of the form of the electronic tag of the present invention. is there.
- FIG. 2 (a) is a plan view showing an example of a form of a non-contact type IC tag
- FIG. 2 (b) is a plan view showing an example of a form of a non-contact type IC tag.
- FIG. 3 is a cross-sectional view showing the distance between the center of the non-contact IC tag and one end of the magnetic tag.
- FIG. 4 shows the relationship between the distance between the center of the non-contact IC tag used in the electronic tag of the present invention and one end of the magnetic tag and the maximum communication distance of the non-contact IC tag. It is the shown graph.
- FIG. 1 shows an example of an electronic tag according to the present invention.
- FIG. 1 (a) is a plan view of the electronic tag
- FIG. 1 (b) is a sectional view thereof.
- the electronic tag of this embodiment is a wireless communication IC chip 1 and a non-contact type IC tag 3 composed of a transmission / reception antenna 2 to which the IC chip 1 is electrically connected to a magnetic tag 4 via an adhesive layer 5. It is a stacked structure.
- FIG. 2 shows an example of a non-contact IC tag suitable for the present invention.
- Fig. 2 (a) and Fig. 2 (b) are radio wave type non-contact IC tags using 2.45 GHz microwaves.
- Radio contactless IC tags that use microwaves of 400 MHz or higher can obtain good communication characteristics by using a dipole antenna whose antenna shape is a rod shape. Therefore, the tag shape can be reduced.
- the antenna has a coil shape, and thus becomes a flat plate with a certain area. Therefore, the operating frequency of the non-contact type IC tag used in the present invention is preferably 400 MHz or more.
- the non-contact type IC tag used in the electronic tag of the present invention is a radio wave type non-contact type IC tag. As shown in FIG. 2, impedance matching with the IC chip is performed on the transmission / reception antenna substrate, which is good. L-shaped and T-shaped excitation slits 6 have been machined to obtain a long communication distance. In the electronic tag of the present invention, it is preferable that the excitation slit does not overlap the magnetic tag. That is, with certain L-shaped and T-shaped excitation slits, as shown in Table 1, when the excitation slit overlaps with a magnetic tag, impedance matching cannot be achieved, and a non-contact type IC tag cannot be connected. This is because the communication performance may deteriorate. Except when designing an excitation slit that takes into account the overlap with the magnetic tag, the communication performance of the non-contact IC tag is likely to deteriorate due to the overlap of the excitation slit.
- the electronic tag of the present invention uses a magnetic tag as a booster antenna for a non-contact type IC tag.
- a booster antenna is an auxiliary antenna that is provided to improve the communication characteristics of a non-contact IC tag.
- the IC tag and the magnetic tag are stacked via an insulating layer, so that when a high frequency is applied, the transmission / reception antenna of the non-contact IC tag and the magnetic tag are electromagnetically coupled, and the magnetic tag is turned off.
- It can be used as a booster antenna for contact IC tags and can improve the communication distance.
- the use of magnetic tags as booster antennas makes it possible to reduce the size and price of non-contact IC tags. By conserving materials, it is possible to reduce energy consumption related to material production and processing. This has the effect of reducing a series of environmental impacts (for example, CO emissions) leading to the use of manufacturing power and disposal.
- Such a booster antenna effect is sufficient if a part of the transmission / reception antenna of the non-contact type IC tag overlaps with a part of the magnetic part of the magnetic tag.
- the magnetic part of the magnetic tag has electrical conductivity in the frequency band of the radio wave used by the non-contact IC tag. As a result, the magnetic part effectively exhibits an antenna effect or a booster effect.
- ⁇ Length force of the magnetic part of the magnetic tag Must be longer than the antenna length of the non-contact IC tag.
- the transmission / reception antenna of the non-contact IC tag is made of a non-magnetic material. As a result, the non-contact type IC tag does not adversely affect the magnetic field.
- the non-contact IC tag and the magnetic tag are arranged from the center of the non-contact IC tag and one end of the magnetic tag when the operating frequency of the non-contact IC tag is 2.45 GHz.
- the distance is in the range of 20 mm to 50 mm.
- Fig. 3 is an explanatory diagram of the arrangement of both, and Fig. 4 shows the relationship between the arrangement of both and the maximum communication distance.
- Fig. 3 shows the distance D between the center of the non-contact IC tag and the single part of the magnetic tag.
- FIG. 4 shows a good range R1 and a particularly good range R2.
- the distance from the center of the non-contact type IC tag and one end of the magnetic tag is 30mm ⁇ 4 In the case of Omm, the best characteristics can be obtained, which is a particularly suitable arrangement.
- the transmission / reception antenna of the non-contact type IC tag used for the electronic tag of the present invention can be made of aluminum or a metal containing copper. These metals are inexpensive, have good workability such as etching, and are generally suitable as antenna materials for obtaining good characteristics.
- the wireless communication IC chip used in the electronic tag of the present invention comprises the individual identification information by ROM. This is because if the wireless communication IC chip is configured with only a unique ID by ROM and managed on the network, an IC chip having an IC that is small, inexpensive, and cannot be tampered with can be realized. Since such an IC chip has low cost and high convenience, there are cases where a greater effect can be exhibited by adopting it as the IC chip of the present invention.
- An electronic tag comprising a non-contact IC tag comprising a wireless communication IC chip and a transmission / reception antenna and a magnetic tag according to the present invention has both the anti-theft and merchandise management functions and is troublesome to attach to an adherend. It is possible to realize an electronic tag that is thin and inexpensive.
- a non-contact type IC tag with an antenna having a shape shown in Fig. 2 (b) having a length of 15 mm was prepared.
- the IC chip used was a “mu chip” sold by Hitachi, Ltd.
- This non-contact type IC tag is pasted via a commercially available double-sided tape with a thickness of 0.17 mm so that the distance from the end of the 130 mm long magnetic tag to the center of the non-contact type IC tag is 35 mm. Attach an electronic tag. At this time, the excitation slit of the non-contact IC tag was not overlapped with the magnetic tag. The size of this electronic tag was 4 mm wide.
- the above electronic tag is attached to the spine of an lcm-thick book with adhesive tape, an IC tag reader (MRJ300, output 300mW, manufactured by Hitachi Kokusai Electric) and an antenna (linear polarization type 1 patch antenna,
- the communication distance was measured using PA1-2450ASA (manufactured by Hitachi Kokusai Electric). As a result, the communication distance was 80 mm. Furthermore, it was detected when it passed through a gate (width 90cm) that senses magnetism.
