An electronic apparatus includes a rectangular or substantially rectangular plate-shaped housing including a first side and a second side which are long sides and a third side and a fourth side which are short sides, and an antenna device. The antenna device includes a first coil including a first coil conductor and a second coil including a second coil conductor. A portion of the first coil overlaps with the second coil opening, a portion of the second coil overlaps with the first coil opening, a straight line connecting a center of gravity of the first coil opening and a center of gravity of the second coil opening intersects with the third side and the fourth side, and the center of gravity of the second coil opening is closer to the third side than the center of gravity of the first coil opening.

Electronic apparatus

An inductor bridge includes a flexible substrate and a coil defined by a conductor pattern provided on or in the flexible substrate, and connects a plurality of circuit portions. The flexible substrate includes a rigid portion and a flexible portion, the rigid portion being wider than the flexible portion. The rigid portion includes the coil and a joining portion connected to another circuit. The coil includes two coil portions located at different positions in plan view, a flexible portion is located adjacent to one side of the rigid portion, and at least two coil portions of the plurality of coil portions are located on the one side when viewed from the joining portion.

Inductor bridge and electronic device

In an antenna device, a first coil conductor portion of a coil conductor faces a planar conductor to at least partially overlap with the planar conductor when viewed in a plan view. A second coil conductor portion of the coil conductor does not overlap with the planar conductor when the planar conductor is viewed in the plan view. On a straight line passing a center of gravity of a coil opening of the coil conductor when the planar conductor is viewed in the plan view, a first distance between the first coil conductor portion and a first edge is shorter than a second distance between the first coil conductor portion and a second edge. The second distance is shorter than a third distance between the center of gravity of the coil opening and a second edge on the straight line passing the center of gravity of the coil opening.

Antenna device and electronic device

An antenna device includes a first planar conductor, a second planar conductor that opposes the first planar conductor in a parallel or substantially parallel arrangement, and a coil element with a winding axis that extends in a direction parallel or substantially parallel to the first planar conductor and the second planar conductor, and includes a first coil opening end and a second coil opening end that opposes the first coil opening end. The first planar conductor includes a conductor outer edge, and a conductor opening including a portion that is continuous with the conductor outer edge. At least a portion of the conductor opening is positioned inside a conductor overlapping region. The first coil opening end of the coil element does not overlap the second planar conductor, and the second coil opening end of the coil element overlaps the conductor opening and the second planar conductor.
