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;
a transmission line comprising a first transmission line and a second transmission line that extend in different directions being connected to the radiator;
an upper parasitic element adjacent to an upper portion of the radiator; and
a lower parasitic element adjacent to a lower portion of the radiator and the transmission line,
wherein the first transmission line having a first feeding portion, and the second transmission line having a second feeding portion, where the first feeding portion and the second feeding portion serve as antenna ports to which feeding signals of different phases are applied, and the feeding signals of different phases are applied to the first transmission line and the second transmission line.
