    摘要： The present invention provides an RFID tag with which it is possible to extend a communicatable distance by a simple and highly reliable antenna connection. This RFID tag (1) comprises an RFID tag device (20) created by mounting an IC for RFID tags on a substrate, and a sheet antenna (10) which includes an antenna conductor (12) and to which the RFID tag device is secured. The substrate of the RFID tag device (20) has a first surface conductor, a second surface conductor arranged between the first surface conductor and the antenna conductor, and a short-circuit conductor for short-circuiting the first surface conductor and the second surface conductor together, the direction of the second surface conductor that faces the center of the second surface conductor from the connecting part of the short-circuit conductor facing the longitudinal direction (X0) of the antenna conductor.

    摘要： The wireless communication apparatus includes an antenna and a communication unit disposed inside the antenna. The antenna includes: a first conductor; a second conductor coupled to the first conductor; a third conductor coupled to the first conductor and aligned with the second conductor; a fourth conductor between the second conductor and the third conductor, the fourth conductor being located apart from the second conductor and the third conductor; a first connection conductor including one end connected to the first conductor and the other end connected to the second conductor; a second connection conductor including one end connected to the first conductor and the other end connected to the third conductor; and a power feeding conductor including one end connected to a feeding point and the other end connected to a conductor facing the feeding point among the first conductor, the second conductor, the third conductor, and the fourth conductor. The communication unit is disposed inside the antenna at a position where a magnetic field strength is relatively high.

    摘要： An RFID tag (1) includes an RFID IC (80), flexible substrates (10, 20) including first wiring conductors (11, 12, 13a to 13d, 14a to 14d, 21, 21n, 22, 23a to 23d, 24n) and rigid substrates (30, 40) including second wiring conductors (31a to 31d, 31n, 41a to 41d, 41n). Substrate surfaces (10A, 20B) of the flexible substrates (10, 20) include first regions (A1, A2) connected to the rigid substrates (30, 40) and second regions (B) that include opposite surfaces (10B, 20A) and are not connected to the rigid substrates (30, 40). First conductor portions (11, 12) and second conductor portions (21, 22) included in the first wiring conductors are electrically connected to each other via the second wiring conductors. The RFID IC (80) is connected to the first wiring conductors, the second wiring conductors, or both the first wiring conductors and the second wiring conductors.
