An antenna structure includes a substrate, a grounding surface and an antenna module. The substrate includes a first surface and a second surface. The antenna module is disposed on the second surface and includes a feeding point, a micro strip, n radiators and n coupling elements. The micro strip extends along a first axial direction and includes a first end, a second end, a first segment and a second segment. A width of the first segment is smaller than a width of the second segment. The n radiators are staggeredly connected to two sides of the micro strip along the first axial direction. The widths of the n radiators from the first end to the second end along the first axial direction are increased first and then decreased. The n coupling elements are separated from the micro strip and the n radiators.
