1. An antenna unit, comprising:
a first substrate and a second substrate disposed opposite to each other, wherein a region facing the first substrate and a region facing the second substrate together form a phase shifting region; in a first direction, the first substrate is formed with a first step region protruding from the phase shifting region, and the first step region is used for connecting a radio-frequency signal terminal; and in a second direction, the second substrate is formed with a second step region protruding from the phase shifting region, and an included angle between the first direction and the second direction is greater than or equal to 0° and smaller than 180°; wherein in a direction perpendicular to a plane where the first substrate is located, at least part of the first step region does not overlap at least part of the second step region;
a plurality of phase shifting units, wherein the plurality of phase shifting units are distributed in an array and are located in the phase shifting region, and each phase shifting unit is used for radiating a radio-frequency signal; and
a driver circuit, wherein at least part of the driver circuit is disposed in the second step region and the driver circuit is electrically connected to each phase shifting unit to adjust the radio-frequency signal radiated by each phase shifting unit.
