    摘要： The pattern line width of a coil is partially widened in a predetermined dimension and wiring patterns of a coil on the surface side and a coil on the rear side are arranged so as not to be in overlapped positions. Consequently, a direct current resistance of the coil can be reduced and an adverse influence by a self resonance of the coil on a communication can be reduced.

    摘要： Provided is a portable information device having an RFID, the device being a device in which no effect is produced on original communication of the portable information device for which an EMC measure is taken, the device having good productivity, and the device keeping communication distance without damaging portability. A place where an antenna is set is located on the side of a battery cover of a battery receiving section to make the communication distance of an incorporated RFID long. A circuit configuration wherein a condenser for resonance is connected to both ends of the antenna coil and an IC is connected to an intermediate tap of the antenna coil is made so as to make it unnecessary that the resonance frequency of the RFID is individually adjusted and make the production of the RFID easy. A magnetic material sheet is arranged between the antenna coil and a battery to ensure a magnetic circuit for causing a magnetic flux from an external apparatus to pass through the antenna coil of the RFID and make the Q of the resonance circuit high.

    摘要： In an RFID (contactless identification) having a resonant circuit, the resonant frequency is directly affected by variations in the input capacitance of an IC chip due to certain manufacturing factors, causing a direct influence on a power reception efficiency and a communication distance. Thus, an RFID is provided for eliminating a step of correcting such variations, reducing the manufacturing cost, and efficiently receiving the power. An IC chip is connected to an intermediate tap of an antenna coil in series through a capacitor. Alternatively, the capacitor is replaced with two capacitors, through one of which the IC chip is connected to the intermediate tap of the antenna coil.
