The present disclosure provides an antenna element and an electronic device, where the antenna element includes: a substrate with a ground plate; a horizontally polarized dipole antenna including a first antenna branch and a second antenna branch, where the first antenna branch and the second antenna branch are disposed in the substrate at intervals, and the first antenna branch and the second antenna branch are disposed on a plane on which the ground plate is disposed; and a first feeding structure, where the first antenna branch and the second antenna branch are electrically connected to the ground plate through the first feeding structure; where the ground plate is spaced apart from both the first antenna branch and the second antenna branch, and a side edge of the ground plate that faces the first antenna branch and the second antenna branch is a concave side edge. In the present disclosure, a side edge of the ground plate that faces horizontally polarized dipole antenna may form a concave reflection surface, and most beams of the horizontally polarized dipole antenna can be radiated toward a front end, thereby improving a reflection effect of the ground plate for an antenna signal, so that the horizontally polarized dipole antenna can reach a radiation requirement of high directivity.
