1. An antenna, comprising:
a substrate having a square shape including first to fourth corners;
a radiating part disposed on the substrate and including a first radiating part and a second radiating part for radiating a wireless signal;
a first feeding line for applying the wireless signal to the first radiating part and having a first extension line;
a second feeding line for applying the wireless signal to the second radiating part and having a second extension line vertically intersecting with the first extension line; and
a ground part disposed on the substrate by being spaced apart from the radiating part and having at least a portion of a boundary area in a stair shape, the ground part comprising a shared ground part disposed along a diagonal from the first corner to the third corner, located between the first radiating part and the second radiating part, and performing impedance matching of the first radiating part and the second radiating part,
wherein the first radiating part is disposed perpendicular to the second radiating part with the shared ground part in between.
