1. A waveguide antenna, comprising:
a base part including an accommodation portion that is accommodates an integrated circuit and configured to separate an output of the integrated circuit into a first electromagnetic wave and a second electromagnetic wave having different frequencies from each other;
a waveguide part provided on the base part and including a first waveguide and a second waveguide that guide the first electromagnetic wave and the second electromagnetic wave in different directions; and
a cover part provided to cover at least a part of the waveguide part and including a first directional surface to which the first electromagnetic wave is radiated and a second directional surface to which the second electromagnetic wave is radiated,
wherein the waveguide part further includes:
a main body in which the first waveguide and the second waveguide are formed, and
wherein a transmission guide portion for the first waveguide and the second waveguide is formed on one side of the main body, and a reception guide portion for the first waveguide and the second waveguide is formed on another side of the main body.
