Abstract
To provide an antenna device whose performance can be improved.SOLUTION: An antenna device includes a first antenna and a second antenna. The first antenna includes: a first substrate including a first surface along a first direction and a second direction; and a plurality of first elements aligned along the second direction. The second antenna includes: a second substrate including a second surface along the first direction and a third direction; and a plurality of second elements aligned along the third direction. The third direction intersects a flat surface which includes the first direction and the second direction. One of the plurality of first elements overlaps the second substrate in the third direction.SELECTED DRAWING: Figure 1
