摘要： In antenna device, a coil conductor of an antenna coil module and a conductor layer at least partially overlap. A current flows in the conductor layer to block a magnetic field generated by a current flowing in the coil conductor. A current flows along the periphery of a slit and around the periphery of the conductor layer due to a cut-edge effect. Since magnetic flux does not pass through the conductor layer, magnetic flux attempts to bypass the conductor layer along a path in which the conductor opening of the conductor layer is on the inside and the outer edge of the conductor layer is on the outside. As a result, the magnetic flux generates large loops that link the inside and the outside of a coil conductor of an antenna on a reader/writer side to couple an antenna device and the antenna on the reader/writer side.

摘要： In a communication circuit, an RFIC includes an IO terminal and a control IC includes an IO terminal. A variable capacitance element includes control terminals, a capacitance element with a capacitance value that is determined according to a control voltage, and a resistance voltage divider circuit configured to generate the control voltage by dividing a voltage inputted to the control terminals. One of the RFIC and the control IC supplies control data to the variable capacitance element via a signal line. The variable capacitance element, along with an antenna coil, constitutes an antenna circuit of an LC parallel resonance circuit, and sets a resonant frequency of the antenna circuit to be a predetermined frequency.

摘要： There is provided an antenna apparatus capable of stably communicating with a communication partner and increasing the maximum possible communication range even when the antenna apparatus is relatively smaller than an antenna in the communication partner and the two antennas are disposed in close proximity on the same axis. A magnetic flux passing through a coil aperture of an antenna coil passes through a conductor aperture of a conductive layer, but the magnetic flux does not pass through the conductive layer. Accordingly, the magnetic flux is diverted to a path in which the conductor aperture of the conductive layer is the inside and the outer edge of the conductive layer is the outside. As a result, the magnetic flux passing through the coil aperture of the antenna coil makes a relatively large loop and links the inside and the outside of a coil conductor in an antenna in a communication partner with the antenna apparatus.

摘要： An electronic device includes a high-frequency transmission line member and a housing. The high-frequency transmission line member includes a flexible substrate, a signal conductor, and a ground conductor along the signal conductor. The housing is defined by a member separate from the high-frequency transmission line member and located at one principal surface side of the high-frequency transmission line member. The high-frequency transmission line member includes a first portion along the housing to face the housing, and a second portion spaced apart from the housing more than the first portion. The ground conductor is not provided at one principal surface side of the signal conductor in the first portion and is provided at least in the second portion.
