    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: The planer antenna includes: a linear radiating antenna element to which electric power is to be supplied; and multiple linear parasitic antenna elements to which electric power is not to be supplied. The parasitic antenna elements are disposed at a position at which the radiating antenna element and the parasitic antenna elements cross each other without contact. The parasitic antenna elements lying in a direction in which the radiating antenna element and the parasitic antenna elements cross each other, and each of the crossing portions of said plural parasitic antenna elements, which portions cross said radiating antenna element, are bent in such a manner that the crossing portions of the parasitic antenna elements are in parallel with the radiating antenna element. Thus, it is possible to provide a planer antenna which can obtain a good circularly polarized wave with a simple construction. In addition, the planar antenna can be downsized.

    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.
