    Abstract: Embodiments of the present disclosure disclose a radio wave radiating device including multiple radiating portions and an antenna having bending patterns.
    As the multiple radiating portions are provided, optimal radiation efficiency can be provided at plural frequency bands.
    Further, due to the bending patterns, a total length of a portion disposed between an earth terminal and a transmission connector in the antenna is longer than a distance between the earth terminal and the transmission connector

    Abstract: The present disclosure relates to an oven having a plurality of antennas and a method for controlling the same. The oven according to an embodiment of the present disclosure includes a single control unit for integrally controlling a plurality of antennas. The control unit calculates a ratio of intensity of radio wave radiated into a cavity through each antenna and intensity of radio wave reflected from the cavity, and uses the ratios to adjust a frequency of a radio wave to be radiated. Accordingly, as a cooking process is carried out, radio wave of an optimal frequency for heating a cooking material can be incident on the cooking material. Accordingly, the cooking process can be performed quickly and efficiently.

    Abstract: An oven includes a housing provided therein with a cooking space and having an upper frame that defines an upper wall in the cooking space, a heating unit installed adjacent to the upper frame and configured to transfer heat to the cooking space, and a plurality of antennas installed at one side of the upper frame and configured to emit radio waves, transmitted from a radio wave generator in electrical connection to an external power source for radio wave generation, toward the cooking space. The heating unit extends to have a predetermined pattern forming a closed area, and is provided with a support member installed to be in contact at a plurality of points therewith.
