    摘要: There is provided an antenna device for transmitting a radio wave to a tag capable of receiving the radio wave includes a first layer, a second layer, and a first plate which is disposed on or above the second layer. These are electrically conductive. The second layer is disposed apart from the first layer and includes a plurality of non-electrically conductive portions to generate an electromagnetic wave travelling along a first axis above the second layer. Further, the first plate is disposed on or above the second layer to allow the tag to receive the radio wave transmitted from the antenna.

    摘要: An information processing apparatus (2) has a contactless reader/writer (90), which includes a coil antenna (110) having a plurality of turns for transmitting and/or receiving an RF modulated carrier signal, by magnetic coupling. The coil antenna (110) is coupled to a transceiver (92) and is disposed in a space within a case (10) between an electric shield (70) and a casing (78) of the case (10). The coil antenna (110) is wound about one center axis (C1) over a predetermined length (L1) to have a generally tubular shape of a predetermined diameter and a predetermined number (N1) of turns, and has a coil plane (P1) at one end of the predetermined length. The electric shield does not have any part present between the part of the casing facing the coil plane located on the one center axis and the electric shield (70), and the outer side portion of the coil antenna (110) is disposed, being spaced from said electric shield by a predetermined distance (ds2).

    摘要: A FM-CW radar device is provided for frequency-modulating a high frequency signal with a modulation signal, transmitting the modulated high frequency signal, receiving a signal reflected by a target object and frequency-modulating the reflection signal with a signal generated by a local oscillator signal source provided by branching a portion of the transmitting signal. A modulator is disposed between a radar transmitting section and a transmitting antenna. The modulator modulates the transmitting signal with a second frequency which is far lower than the radar transmitting frequency and twice as much as the sum or the difference of a Doppler frequency generated by a relative propagation velocity and a beat frequency generated by a propagation delay time. A first frequency converter frequency modulates the received signal reflected by the target object with the local oscillator. A second frequency converter frequency modulates the received signal with the second frequency, the second frequency being far lower than the radar transmitting frequency and twice as much as the sum or the difference of a Doppler frequency generated by a relative propagation velocity and a beat frequency generated by a propagation delay time.
