Abstract: A rotating antenna (105a) includes: a ceiling surface (109) and a side-wall surface (110) that constitute a waveguide structure (108); and a horn (113) that radiates a microwave into a heating chamber. The rotating antenna (105a) further includes a flange (112) that is formed on a periphery of the side-wall surface (110) so as to face a bottom surface (111), which is an inner wall surface of the heating chamber, and so as to surround the side-wall surface (110). The flange (112) has choke sections (117) that reduce a leakage of the microwave. This configuration can generate a relatively low impedance region so as to surround the side-wall surface (110), thereby enhancing a leakage reducing performance of the rotating antenna (105a) and increasing directivity of the microwave radiated from the rotating antenna (105a). Consequently, if a part of substances to be heated arranged on a plate is a food that a user does not want to warm, the rotating antenna (105a) selectively heats an area in which a food that the user wants to warm is present but hardly heats the food that the user does not want to warm.

Abstract: Microwave oven (20) includes waveguide (3) having an E-bend structure, and multiple openings (4a, 4b). Waveguide (3) has first section (3a) for propagating a microwave from magnetron (2) toward heating chamber (1), and second section (3b) of which wide plane abuts on the outer wall of heating chamber (1). Multiple openings (4a, 4b) are disposed on a lateral face of heating chamber (1). Openings (4a, 4b) allow waveguide (3) to communicate with heating chamber (1), and include at least one circularly-polarized-wave opening (4a) for generating a circularly polarized wave. A cross section of first section (3a) orthogonally intersecting tube axis (7a) of first section (3a) is projected virtually along tube axis (7a) of first section (3a) onto a lateral face of heating chamber (1), and circularly-polarized-wave opening (4a) is formed such that its center is located outside the resultant projected region defined by this projection. The foregoing structure allows this compact size waveguide to generate a circularly polarized wave more positively.
