Abstract
An antenna device includes a power supply coil coupled to a first power supply circuit operating in a first frequency band, a first conductive member including a first main surface, a second conductive member including a second main surface, a third conductive member, and first connections. The second main surface of the second conductive member is disposed with at least a portion thereof opposing the first main surface. The third conductive member has an area that is smaller than an area of the first conductive member when viewed in a direction perpendicular or substantially perpendicular to the first main surface. The first conductive member, the third conductive member, and the first connections define a loop of a magnetic field antenna in the first frequency band. The power supply coil is closer to the third conductive member than to the first conductive member when viewed in the Z-direction.
