1. A wearable antenna, comprising:
an upper substrate made of a solid material;
an inner open ring radiator formed in a ring shape on an upper surface of the upper substrate and having a first slit formed therein to open a partial area;
an outer open ring radiator formed in a ring shape having the same center as the inner open ring radiator and having a larger radius on the upper surface of the upper substrate, and having a second slit formed therein to open a partial area;
a feeding portion formed on a lower surface of the upper substrate and transmitting a feed signal applied from an input port to each of the two open ring radiators through two vias penetrating the upper substrate;
a lower substrate spaced apart from a lower surface of the upper substrate by a predetermined distance and made of a flexible material; and
a ground plane formed on a lower surface of the lower substrate,
wherein the first slit and the second slit are formed in a direction extending perpendicularly to each other.
