1. An antenna structure, comprising:
a dielectric layer; and
a plurality of antenna units arranged on a top surface of the dielectric layer, each of the plurality of antenna units comprising:
a radiator comprising convex portions and concave portions;
a first transmission line and a second transmission line extending in different directions to be connected to the radiator;
an upper parasitic element adjacent to an upper portion of the radiator, the upper parasitic element comprising a first upper parasitic element and a second upper parasitic element separated from each other; and
a lower parasitic element adjacent to a lower portion of the radiator,
wherein the first upper parasitic element and the second upper parasitic element are disposed to be adjacent to different concave portions of the concave portions.
