    摘要: An antenna device includes: a first planar antenna for a linearly polarized wave, the first planar antenna including a first feeding portion; and a second planar antenna for a linearly polarized wave, the second planar antenna including a second feeding portion that overlaps the first feeding portion in a plan view when viewed in a direction perpendicular to a predetermined surface of the first planar antenna, wherein the linearly polarized wave of the first planar antenna and the linearly polarized wave of the second planar antenna intersect each other.
