1. An antenna structure with a wide beamwidth for covering an operation frequency band, comprising:
a dielectric substrate, having a first surface and a second surface opposite to each other;
a ground plane, disposed on the second surface of the dielectric substrate;
a first radiation element, disposed on the first surface of the dielectric substrate, wherein a first notch is formed on the first radiation element;
a plurality of first conductive via elements, penetrating the dielectric substrate, wherein the first conductive via elements are coupled between the first radiation element and the ground plane; and
a first feeding connection element, coupled to the first radiation element, wherein the first feeding connection element extends into the first notch of the first radiation element;
wherein the first radiation element has a first edge, a second edge, a third edge, and a fourth edge, and the first notch is positioned at the fourth edge;
wherein a distance between any two first conductive via elements adjacent to the first edge of the first radiation element is from 0.45 to 0.55 wavelength of the operation frequency band.
