Abstract: An antenna structure includes a dielectric substrate, a ground layer and a radiation layer located at two opposite sides of the dielectric substrate. The ground layer has two first gaps which are symmetrical about a central axis of the antenna structure in a first direction to introduce a radiation zero. The radiation layer has two second gaps which are symmetrical about the central axis, edges of the two second gaps are aligned with edges of the radiation layer in a second direction to introduce another radiation zero. The second direction is perpendicular to the first direction.
