Antenna element and electronic device

An electronic device, comprising at least two antenna elements, wherein one of the at least two antenna elements comprises:

• a substrate, wherein the substrate has a ground plate;
• a first vertically polarized dipole antenna, wherein the first vertically polarized dipole antenna comprises a first antenna branch and a second antenna branch, and the first antenna branch and the second antenna branch are disposed in the substrate at an interval;
• a second vertically polarized dipole antenna, wherein the second vertically polarized dipole antenna comprises a third antenna branch and a fourth antenna branch, and the third antenna branch and the fourth antenna branch are disposed in the substrate at an interval;
• a reflector, wherein the reflector comprises several reflection pillars, and the several reflection pillars are arranged in the substrate at intervals along a parabola;
• and
• a first feeding structure, wherein the first feeding structure electrically connects each of the first antenna branch, the second antenna branch, the third antenna branch, and the fourth antenna branch to the ground plate, wherein
• the first antenna branch, the second antenna branch, the third antenna branch, and the fourth antenna branch are all located on a focus side of the parabola;
• and
• lengths of the first antenna branch and the second antenna branch are both less than lengths of the third antenna branch and the fourth antenna branch.
