    摘要: A battery-free non-contacting information card of a relatively simple arrangement which prevents an IC chip or the like from being destroyed by an excess voltage. This non-contacting information card includes a resonance circuit (3) for receiving a carrier signal (e.g., FSK signal) modulated on the basis of information supplied from a card reader/writer (2), an information processing systems (5), (6), (7) for obtaining information from the carrier signal and a rectifier systems (13) for obtaining a voltage by rectifying the carrier signal, wherein the non-contacting information card can be operated by the voltage obtained at the output side of the rectifier circuit (13). The resonance circuit (3) includes a variable capacitive element (3d). A resonance frequency of the resonance circuit (3) is varied by varying the capacity value of the variable capacitive element (3d) in response to the voltage value obtained at the output side of the rectifier circuit (13) to thereby make the voltage value obtained at the output side of the rectifier circuit (13) substantially constant.

    摘要: In a multiple loop antenna comprising a combination of a plurality of loop antennas, at least one factor among the diameter of each loop antenna, the number of turns thereof, the direction thereof, the effective permeability thereof, the relative values of electric currents of loop antennas and the phase difference of electric currents is controlled in such a way that the magnetic field intensity within the range extending from the multiple loop antenna to the distance of transmission wavelength of the multiple loop antenna decreases in inverse proportion to the n-th power (n>3) of the distance from the multiple loop antenna. This makes it possible to obtain a multiple loop antenna that has a high-intensity magnetic field within the predetermined communication zone but can steeply decrease the magnetic field intensity according to an increase in distance from the antenna and surely control the magnetic field intensity to be not greater than a stated value on the outside of the communication zone.

    摘要: A short-distance communication antenna can satisfactorily transmit and receive an information signal within a regulation range of the radio law. Also, the short-distance communication antenna provided on a card reader/writer enables the card reader/writer to communicate with a non-contacting information card without being limited by the direction of the non-contacting information card upon reception. This short-distance communication antenna includes a plurality of magnetic poles disposed on a magnetic member and to and from which a magnetic flux is transmitted and received, and a coil for transmitting or transmitting and receiving the information signal mounted on at least one of the magnetic poles. Further, the short-distance communication antenna includes a housing having an aperture to and from which a magnetic flux is transmitted and received, and a coil for transmitting or transmitting and receiving the information signal mounted on said housing. Furthermore, there are also provided methods of manufacturing and of using the above short-distance communication antenna. In this case, the most specific feature of this invention is that a magnetic flux of the communication antenna is closed and a communication area is limited.
