    摘要： An RF tag is disclosed that includes an antenna and an integrated circuit connected to the antenna. The antenna includes a first radiating element, a second radiating element, a feeding part connected in series between the first and second radiating elements, and an impedance control part connected parallel to the feeding part. An auxiliary radiating element connected to one or both of the first and second radiating elements is used for radio communication with the integrated circuit before completion of the RF tag, and is not used for radio communication after the completion of the RF tag.

    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： A dipole part of a length shorter than half of an antenna resonance wavelength is placed so as to be rolled and enables a feeding part 11 to feed a chip. An inductance part 12 for adjusting the inductance of the antenna is provided so as to sandwich the feeding part 11. The inductance 12 is provided using an empty space of the inside of the rolled dipole part. By providing the inductance part 12, the inductance of the antenna can be adjusted so as to resonate at a predetermined frequency with the capacitance of the chip connected to the feeding part 11. At this time, although the radiation resistance of the antenna becomes extremely large according to calculations, it is actually almost the same as the resistance of the chip due to loss, and the power received by the antenna can be provided to the chip.

    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.
