Abstract (en)
An antenna device (100) includes: an antenna element (20) of a folded dipole antenna, the antenna element being a folded flat metal plate and having a folded structure; and a board (30) on which the antenna element is mounted. The antenna element includes an antenna element body (21). An unfolded shape of the antenna element body is in mirror symmetry with respect to a line of symmetry (L1). The antenna element body includes side parts (21a, 21b) parted by the line of symmetry, each of the side parts having four or more folding lines (B1 to B5).
