FEEDING COIL, ANTENNA DEVICE, AND ELECTRONIC APPARATUS

摘要

The present invention is provided with: a first coil antenna (10) and a second coil antenna (20) of which winding axis directions are not perpendicular to each other; and a feeding coil (30) having a winding axis which is in a direction perpendicular to the winding axis of the first coil antenna (10). The feeding coil (30) is placed between the first coil antenna (10) and the second coil antenna (20) in the height direction (winding axis direction) thereof. A first coil opening (E1) is closer to a coil opening (AP1) of the first coil antenna (10) than a second coil opening (E2). The second coil opening (E2) is closer to a coil opening (AP2) of the second coil antenna (20) than the first coil opening (E1). The first coil antenna (10) and the second coil antenna (20) are connected to each other in a polarity in which the magnetic fluxes with respect to the winding axis direction of the first coil antenna (10) are in-phase.
