1. An antenna element comprising:
a dielectric layer;
a radiation electrode arranged on an upper surface of the dielectric layer and comprising a first mesh structure; and
a dummy electrode arranged on the upper surface of the dielectric layer and comprising a second mesh structure,
wherein the first mesh structure comprises a radiation unit cell having a polygonal shape, and the second mesh structure comprises a dummy unit cell having a polygonal shape,
wherein the polygonal shape of the radiation unit cell and the polygonal shape of the dummy unit cell are substantially identical, and
wherein at least one of the radiation electrode and the dummy electrode satisfies Equation 1 below
