1. A radio wave radiating device, comprising:
a radio wave supply unit configured to transmit a radio wave and extending in one direction, one end of the radio wave supply unit being electrically connected to an external power source;
an earth part spaced apart from the radio wave supply unit by a predetermined distance in a direction intersecting with the one direction, extending in the one direction, one end of the earth part being electrically connected to a ground; and
a radiating element electrically connected to another end of the radio wave supply unit and another end of the earth part, respectively, and configured to radiate the radio wave received from the radio wave supply unit,
wherein the radiating element comprises:
a middle portion connecting the radio wave supply unit and the earth part;
a first radiating portion extending from the middle portion connected to the earth part, in a direction away from the earth part and the middle portion; and
a second radiating portion extending from an end of the middle portion connected to the radio wave supply unit, in a direction away from the radio wave supply unit and the middle portion,
wherein the middle portion comprises a bending pattern extending in a curved shape,
wherein the first radiating portion includes at least one bending pattern extending in the curved shape, and
wherein the second radiating portion includes at least one bending pattern extending in the curved shape.
