Abstract
Disclosed antenna unit includes first substrate and second substrate opposite to each other, phase shifting units and driver circuit. Region facing the first substrate and the second substrate form phase shifting region. In first direction, the first substrate formed with first step region, and used for connecting radio-frequency signal terminal; in second direction, the second substrate formed with second step region, and included angle between the first direction and the second direction greater than or equal to 0° and smaller than 180°. At least part of the first step region does not overlap at least part of the second step region. Phase shifting units used for radiating radio-frequency signal and distributed in phase shifting region, each phase shifting unit. At least part of the driver circuit disposed in the second step region and the driver circuit electrically connected to each phase shifting unit to adjust radio-frequency signal.
