Abstract
Provided is an antenna device. The antenna device includes at least one antenna unit and first connection lines, where each antenna unit includes a first substrate and a second substrate, a region where the first substrate and the second substrate overlap forms a phase shift region in a thickness direction of the first substrate; the second substrate includes a first step protruding from the phase shift region in a first direction, a side of the first step close to the first substrate is provided with multiple first pads arranged in a second direction, the first pads are disposed on a side of the second substrate close to the first substrate, and the first direction intersects the second direction; and the first pads are connected to the first connection lines, and the first pads receive a drive signal output by an external driver circuit through the first connection lines.
