摘要： The purpose of the present disclosure is to provide a cooking appliance in which a shielding filter serving to block microwaves generated from an MW heating module and pass a magnetic field, generated from an IH heating module, therethrough is tightly coupled to a plate. The cooking appliance may comprise: a housing which has a cavity formed therein; a door which is connected to the housing and opens/closes the cavity; an MW heating module which emits microwaves to the cavity; a working coil module which emits a magnetic field to the cavity; a plate in which a center hole for guiding a magnetic field to the cavity is formed; and a shielding filter which is disposed between the plate and the working coil module, wherein the plate has a plurality of grooves formed around the center hole.

摘要： 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-
