Claim 17:
18. An oven, comprising:
a housing defining a cavity;
a radio wave supply unit configured to transmit a radio wave and extending in one direction toward an inner wall of the cavity, one end of the radio wave supply unit being electrically connected to an external power source that is located outside the cavity;
an earth part spaced apart from the radio wave supply unit by a predetermined distance in a direction intersecting the one direction and extending in the one direction to be coupled to the inner wall of the cavity; and
a radiating element electrically connected to another end of the radio wave supply unit and an end of the earth part, respectively, and configured to radiate the radio wave received from the radio wave supply unit toward the cavity,
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 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.
