Abstract: An oven includes a housing that defines a cooking space and that includes an upper frame defining an upper wall facing the cooking space, a heating unit disposed at the upper frame and configured to transfer heat to the cooking space, an antenna disposed at the upper frame and configured to emit, toward the cooking space, radio waves transmitted from a radio wave generator that is electrically connected to an external power source, and a forming part that protrudes upward from the upper frame and accommodates the antenna therein. The forming part covers the antenna from the cooking space.

Abstract: A radio wave radiating device includes: a radio wave supply unit extending in one direction, one end of the radio wave supply unit being connected to a 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 connected to a ground, and a radiating element connected to another end of the radio wave supply unit and another end of the earth part, respectively, and configured to radiate a radio wave received from the radio wave supply unit. The radiating element includes a middle portion connecting the radio wave supply unit and the earth part, a first radiating portion extending in a direction away from the earth part, and a second radiating portion extending in a direction away from the radio wave supply unit.
