- an IC tag also referred to as an RFID tag
- an RFID tag is known.
- the communication method has been changed.
- As a communication frequency a UHF band capable of radio wave communication is used instead of the HF band used so far, and a half-wave dipole antenna is often used as an antenna for an IC tag.
- a half-wave dipole antenna is a dipole antenna in which the antenna length, which is the effective length of an antenna radiation portion (in this application, referred to as an antenna radiation portion), is approximately 1 ⁇ 2 the communication wavelength (for example, a patent) References 1 and 2).
- Fig. 9 shows the basic configuration of a half-wave dipole antenna for IC tags.
- an IC chip mounting part 101 having an IC chip mounting end 103 on which an IC chip (not shown) is arranged, an impedance adjusting part 102 for adjusting the impedance of the antenna, and a pair of antenna radiations Part 11.
- the half-wavelength dipole antenna shown in FIG. 9 is divided by two points where the IC chip mounting portion 101 and the impedance adjusting portion 102 constitute the central branch path 10 and the antenna radiating portion 11 is connected.
- One of the central branch paths 10 having the IC chip mounting end 103 is the IC chip mounting portion 101, and the other is the impedance adjusting portion 102.
- an IC chip does not have a power source and operates with power received by an antenna. For this reason, the antenna radiating unit 11 needs to supply power to the IC chip by impedance matching with an IC chip (not shown) connected to the IC chip mounting end 103 and used.
- an IC tag antenna which is an antenna used for a card or a sheet-like IC tag

- an effective antenna length is ensured by bending the antenna radiating portion to make a meander shape or the like, if a defective portion occurs in a part of the antenna pattern, the current hardly flows even if it is an alternating current.
- the effective antenna length as a whole also changes greatly, so that the current distribution changes greatly.

Therefore, appropriate radiation characteristics can be maintained.
- the effective antenna length changes when a defect occurs in the combined flow path.
- the length of the extending direction of the radiating portion is increased. It can be shortened and the line width can be increased compared to the branch path. In other words, since it is very unlikely that a defective part that completely breaks a thick and short joint flow path at the time of manufacture and use will be produced, it will not affect the antenna size in the extending direction of the radiating part, and it will not be damaged. Is easy.
- the influence on the communication distance due to a change in communication frequency can be suppressed by increasing the line width of the antenna radiating portion.
- the line width is larger than that of the branch path, and in the branch path, a pair of branch paths are connected in parallel, so that the same effect as that of increasing the line width is obtained.
