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.
