    摘要： Provided is a RF tag which can be stored even in a small case having a metal plane. The RF tag is provided with a first line (ABCDEFGH), which is connected to a grounding conductor, forms an electrical closed loop and constitutes a dipole antenna; a power supply circuit connected between a branching point (C) on the first line and the grounding conductor; and a second line (CFGHA) which is connected to the branching point (C), arranged in parallel with the power supply circuit and constitutes an inductor. The position of the branching point of the first line and the second line is adjusted so that impedance of the dipole antenna matches with that of the power supply circuit.

    摘要： To perform high quality wireless communication in which radio wave radiation/reception characteristics do not deteriorate even in the vicinity of a human body and communication of other IC tags is not impeded. A main loop section (11) is a metal foil of elongated loop-shape having an area smaller than the area of a dielectric substrate (30), and mounted to contain the dielectric substrate (30) while covering the surface and side face thereof in the horizontal direction relative to the surface of the dielectric substrate (30) in order to transmit/receive a radio wave. A capacitive load section (12) is a metal foil provided, respectively, at both ends of the main loop section (11) covering the front surface of the dielectric substrate (30) and both ends of the main loop section (11) covering the back surface of the dielectric substrate (30) and has a load of capacitance component. A control section (20) is connected with the main loop section (11) and controls information through a radio wave.

    摘要： An antenna for RFID which can save installation space. The antenna (10) for RFID is provided with an outermost conductive line (11) bent to follow the sides of a rectangle of a prescribed size; and a power supplying conductive line (13), which is arranged parallel to the outermost circumference conductive line (11) close to an inner circumference side, is electrically connected to the outermost circumference conductive line (11) at an end part, and is partially provided with a power supplying part (12). Therefore, the antenna (10) can be stored in the rectangle having the prescribed size, for instance, a card size.

    摘要： Provided is a RF tag with which communication can be made prior to completion of the RF tag. The RF tag is provided with an integrated circuit connected to an antenna. The antenna is provided with a first radiating element, a second radiating element, a power feeding section connected in series between the first and the second radiating elements, and an impedance adjusting section connected in parallel to the power feeding section. An auxiliary radiating element connected to both of or one of the first and the second radiating elements is used for wireless communication with the integrated circuit prior to completion of the RF tag, and the auxiliary radiating element is not used for wireless communication after the completion of the RF tag. After the wireless communication is made by using the first, second and the auxiliary radiating elements, at least a part of the auxiliary radiating element is removed, and thereafter, the auxiliary radiating element does not make contribution to the wireless communication.
