    Abstract: A multilayered substrate includes first, second, and third insulating layers, and a transmission line. The first insulating layer includes first and second surfaces opposite to each other. A signal conductor of the transmission line is on the first surface of the first insulating layer. The second insulating layer is in contact with the first surface of the first insulating layer. The third insulating layer is in contact with the second surface of the first insulating layer. A dielectric loss of the second insulating layer is lower than a dielectric loss of the third insulating layer. A degree of close contact between the first insulating layer and the third insulating layer is higher than a degree of close contact between the first insulating layer and the second insulating layer.

    Abstract: An insulating substrate including a principal surface and coil antennas disposed on the substrate and each including a coil conductor. The coil conductor includes a winding axis in a direction parallel or substantially parallel to the principal surface of the substrate. An auxiliary loop conductor that is connected to the coil conductors of the coil antennas and generates a magnetic flux that is in phase with those of the coil antennas as seen from the direction of the winding axis of the coil conductor is provided in and on the substrate.

    Abstract: An antenna device includes a power feed coil to be connected to a RFIC and a coil antenna that couples with the power feed coil. The power feed coil includes a first power feed coil and a second power feed coil connected to the first power feed coil. The second power feed coil includes a coil opening with a planar or substantially planar shape. The coil antenna includes a coil opening with a planar or substantially planar shape along a plane identical, parallel, or substantially parallel to that of the coil opening of the second power feed coil. The center of gravity of the coil antenna is located within the coil opening of the second power feed coil when viewed in plan view. A winding axis direction of the first power feed coil crosses or intersects with a winding axis direction of the coil antenna. The first power feed coil and the second power feed coil magnetically couple with the coil antenna.

    Abstract: An antenna element includes an insulative substrate including first and second main surfaces arranged in an up-down direction. At least one antenna conductor layer is provided on the first main surface of the insulative substrate. At least one insulative substrate non-forming region is provided between the insulative substrate and the antenna conductor layer in the up-down direction. An insulator layer does not exist in the at least one insulative substrate non-forming region. When seen in the up-down direction, all of an outer boundary of at least one antenna conductor overlaps the at least one insulative substrate non-forming region and is not in contact with the insulative substrate. At least one of the at least one insulative substrate non-forming region includes a void.

    Abstract: In a transmission line, a thickness of a second section is smaller than that of a first section and of a third section. A center of the second section is above a center of the first section and a center of the third section in a laminated body up-down direction. A distance between a second signal conductor layer and a neutral plane of the second section is shorter than a distance between a first signal conductor layer and a neutral plane of the second section and a distance between a third signal conductor layer and a neutral plane of the second section in the laminated body up-down direction. A length of the second signal conductor layer between first and second interlayer connection conductors is equal to or less than about ½ of a wavelength of a high-frequency signal transmitted by the transmission line.
