Abstract (en)

The antenna consists of an electrically conducting spindle (1) which receives magnetron energy at one end and is connected to an emitting surface (2) at the other by a dielectric tee piece (3). Microwaves are directed into the oven from the emitting surface and adjacent portion of shaft and an asymmetric element (4) which rotates with the emitting surface aids a homogeneous heat distribution. An Independent claim is also included for the microwave oven.

Abstract (fr)

L'invention concerne le domaine des antennes pour four à micro-ondes. C'est une antenne comportant un axe (1) conducteur, une surface émettrice (2) conductrice liée à une extrémité de l'axe (1), une jonction diélectrique (3) liant l'axe (1) et la surface émettrice (2) de manière à établir une discontinuité électrique entre l'axe (1) et la surface émettrice (2), la surface émettrice (2) ne présentant pas une symétrie de révolution autour de la direction moyenne (M) de l'axe (1). L'antenne est notamment utilisée dans les fours à micro-ondes de cuisson domestique. <IMAGE>
