    摘要： An RFID tag having a tag antenna and an LSI chip, comprising: a power-supply pattern on which the LSI chip is mounted; a patch antenna that functions as the tag antenna; and a high-frequency connection section that makes a high-frequency connection between the power-supply pattern and the patch antenna. The high-frequency connection section is formed, for example, by forming a slot in the patch antenna, layering one end of a small dipole antenna that functions as the power-supply pattern over the slot so that it crosses over the slot, and supplying power from the small dipole antenna to the patch antenna.

    摘要： In a folded dipole antenna, both ends of a first dipole portion with a feeding portion are connected to both ends of a second dipole portion so that a slot portion may be formed, and the first and the second dipole portion have a width for generating a linearly-polarized wave in a slot mode (in a longitudinal direction) when an RFID chip is mounted on the feeding portion. A terminal of a chip is actually connected to an antenna terminal of the feeding portion of the folded dipole antenna to realize a tag.

    摘要： A crossed dual tag includes two tags each of which comprises, on one plane, a dipole antenna formed with conductors, a feeding part to which an IC chip is connected at the center of the dipole antenna, and a loop-shaped inductance part that is formed between the dipoles of the dipole antenna and connected to the dipoles of the dipole antenna in parallel with respect to the feeding part. The two tags are crossed at right angles, and stacked to contact as closely as possible so that the loops of the inductance parts overlap as wide as possible. A reader/writer of an RFID system sequentially switches the surface of a circular polarized wave of a wireless signal between forward and backward directions, and reads information written to a user memory area from the tag that responds more strongly.

    摘要： In an RFID tag, a ground portion attached to a magnetic recording medium so as to be electromagnetically coupled to a metal surface inside the magnetic recording medium in a high-frequency band, a monopole portion provided on a same plane as the ground portion and inside the ground portion, and a feeding portion connected to one end of the monopole portion and mounting thereon an LSI chip are provided. The ground portion has a ring shape, the monopole portion bent along the ring shape has a length for impedance matching with the feeding portion, and this length can be adjusted by providing a folded portion or a meander portion. Alternatively, the monopole portion may be decentered from the ground portion so as to locate a vicinity of the feeding portion away from the ground portion and to bring a vicinity of the tip portion near to the ground portion, in which case an adjusting portion can be provided at the tip portion of the monopole portion.

    摘要： A meander line antenna formed by folding a conductive pattern of a folded dipole antenna in the shape of meander is disclosed. The basic structure of the meander line antenna includes a bottom half section formed by a folded conductive pattern, and a feeding point arranged approximately at the center of the folded conductive pattern for mounting an IC chip, a top half section consisting of a folded conductive pattern shaped like the bottom half section, a coarse tuning section consisting of two or more short circuit conductive patterns for coarse tuning that connects countering conductive patterns of either or both of the bottom half section and the top half section at a predetermined interval, and a fine-tuning section consisting of two or more short circuit conductive patterns for fine tuning that connect countering conductive patterns of the top half section, the countering conductive patterns being located at a position that counters the feeding point, at a predetermined interval.
