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 smalI dipole antenna to the patch antenna.

摘要： A loop antenna includes a dielectric substrate taking a cuboid form, and a loop part composed of a metal that covers two pairs of facing surfaces of the dielectric substrate. The loop part is formed by leaving a blank portion at the center of one surface of the pair of facing surfaces having a wider area. In the blank portion, a feeding point to an LSI chip and a capacitance part connected to the loop part in parallel to the feeding point are formed. The capacitance part is provided to compensate for an internal capacitance of the LSI chip so that a small LSI chip matches the antenna. A convex part having a length is arranged with a gap within a corresponding concave part to form a large capacitance.

摘要： The present invention relates to a tag-use antenna allowing a miniaturization while maintaining a constant minimal change of a communication distance. The tag-use antenna has a feed part of a folded dipole antenna of a size of 53 mm long and 7 mm wide being connected to, and equipped with, an LSI chip of Rc=500 ohms and Cc=1.4 pF and is covered with plastic resin 13 of the dielectric constant εr=3 and thickness of t=0.75 mm on both sides of the antenna. The dipole part of 1 mm wire path width of the tag-use antenna is formed in a rectangular spiral by being bent inward from both ends at bending parts at four places. The entire length of the dipole antenna when extending the four bending parts straight is featured so as to be shorter than one half of a resonance wavelength of the antenna. An inductance part is formed in the neighborhood of the center of the dipole antenna, and placed in the middle of the dipole antenna, which is formed in said rectangular spiral, of the dipole antenna
