    摘要： A wireless IC device that is operable in a wide band and is suitable for RFID systems includes a radiating plate and an electromagnetically coupled module constituted by a wireless IC that processes transmitted/received signals and a feeding circuit board having a feeding circuit and coupled with the wireless IC. The radiating plate includes a linear electrode bent at a bent portion and apparently sectioned into two linear electrode portions having different lengths. The electromagnetically coupled module is arranged such that the feeding circuit board and the linear electrode portions are electromagnetically coupled. The wireless IC is operated by signals received by the radiating plate, and response signals from the wireless IC are radiated outward from the radiating plate.

    摘要： A test system for a radio frequency IC device includes a radio frequency IC chip and a radiation strip. The characteristics of the radio frequency IC device are measured by bringing the tip of a probe of a test apparatus in direct contact with a portion of the radiation strip and thereby providing a radio frequency signal. The tip of the probe is made to be a flat plate so as to obtain closer and more stable contact with the radiation strip.

    摘要： An antenna includes two feeding points, and includes a loop-shaped loop electrode and an auxiliary electrode electrically connected to the loop electrode and located at a position along the outer circumference of the loop electrode. The first end portion of the auxiliary electrode is electrically connected to the vicinity of one feeding point of the loop electrode. The second end portion of the auxiliary electrode is open. A resonant circuit is defined by the auxiliary electrode and the loop electrode to enhance the impedance of the antenna, compared with a case in which the antenna is configured using the simple loop electrode, and it is easy to achieve impedance matching with the wireless IC.

    摘要： A radio frequency IC device includes a radio frequency IC chip, a feeder circuit substrate, and a radiating plate. The feeder circuit substrate includes a feeder circuit that electrically connects to the radio IC chip and that includes a resonance circuit and/or a matching circuit including inductance elements. The feeder circuit substrate is bonded to the radiating plate, which radiates a transmission signal supplied from the feeder circuit and supplies a received signal to the feeder circuit. The inductance elements are arranged in spiral patterns wound in opposite directions and couple to each other in opposite phases. The radio frequency IC device is able to obtain a radio frequency IC device that is not susceptible to being affected by a usage environment, minimizes variations in radiation characteristics, and can be used in a wide frequency band.
