    摘要: An antenna device includes an antenna coil including a first conductive pattern disposed on a first major surface of a magnetic sheet, a second conductive pattern disposed on a first major surface of a non-magnetic sheet, and an interlayer conductor connecting the first conductive pattern and second conductive pattern. The antenna coil including the first conductive pattern and second conductive pattern defines a spiral or substantially spiral pattern. The antenna device is a resin multilayer structure in which its base body is a laminate of the magnetic layer and non-magnetic layer and the predetermined patterns are disposed inside and outside the laminate.

    摘要: An electromagnetic-coupling module including a radio IC chip and a feeder circuit board on which the radio IC chip is mounted and a feeder circuit including a resonant circuit having a predetermined resonant frequency is attached to an article. The article has a radiation element that radiates a transmission signal supplied from the feeder circuit of the electromagnetic-coupling module via electromagnetic coupling and that supplies a received reception signal to the feeder circuit via the electromagnetic coupling.

    摘要: A high-frequency signal line includes a body with a first layer level and a second layer level; a signal line including a first line portion provided at the first layer level, a second line portion provided at the second layer level, and a first interlayer connection connecting the first line portion and the second line portion; a first ground conductor including a first ground portion provided at the first layer level; a second ground conductor including a second ground portion provided at the second layer level; and a second interlayer connection connecting the first ground portion and the second ground portion. A distance between the first interlayer connection and the second interlayer connection is not less than a maximum distance between the first line portion and the first ground portion and is not less than a maximum distance between the second line portion and the second ground portion.
