    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： A connector-equipped communication module includes a communication module and a connector. The communication module includes a wiring board including antenna-mounted and IC-mounted regions at different positions in a planar view, an antenna element mounted in the antenna-mounted region, a wireless IC and a mounted component mounted in the IC-mounted region, and side terminals in the IC-mounted region and peripheral portions near the IC-mounted region. The connector includes a receiving portion including a placement portion configured to mount the communication module and a wall portion extending around the placement portion, inner wall terminals on an inner side of the wall portion at positions facing the side terminals, and external terminals located outward of the receiving portion and electrically connected to the inner wall terminals. In a state where the communication module is received in the receiving portion, the inner wall and side terminals are fitted so as to contact with each other.

    摘要： An article management system includes multiple reader devices that read the RFID tags attached to the articles. Moreover, a central terminal partitions an article management area into multiple middle areas that are in turn partitioned into small areas, and then causes reader devices arranged in two or more small areas to work in a predetermined order for each small area, to read information of the RFID tags. The range of radio wave interference distance assumed for a reader device in a first middle area partially overlaps with a second middle area. Thus, when causing the reader devices arranged in the first middle area to work in order, the central terminal controls a reader device in the second middle area that lies outside the range of radio wave interference distance from a reader device working in the first middle area.

    摘要： An antenna device includes a first insulating base portion including a spiral antenna pattern, and a second insulating base portion including at least two conductor wires. An insulating layer configured to insulate the conductor wires from the antenna pattern is provided between a first end and a second end of the antenna pattern in a planar view. The insulating layer includes a cut or an opening allowing at least one of the first end and the second end of the antenna pattern to be exposed toward the conductor wires. Electrode portions of the conductor wires are electrically and mechanically connected to the first end and the second end, respectively, of the antenna pattern by a conductive material in the cut or the opening of the insulating layer. The second insulating base portion is more flexible than the first insulating base portion.
