Abstract

L'invention concerne les magnétrons. Il est décrit un magnétron caractérisé par le fait qu'il comprend une structure d'anode comportant de multiples ailettes formées de matière conductrice de l'électricité, supportées par un élément annulaire, pratiquement parallèle à l'axe de cet élément et faisant saillie radialement par rapport à celui-ci, et une douille pratiquement cylindrique, disposée coaxialement à l'élément annulaire et conçue pour tourner relativement aux ailettes, les ailettes et la douille étant conçue pour se chevaucher sur au moins une partie de leur longueur axiale respective, la douille étant munie, dans la partie chevauchante, de multiples ouvertures conçues pour coopérer avec les ailettes lorsque la douille tourne, de manière à faire varier la fréquence à laquelle est accordée le magnétron, au moins une des ouvertures ayant une forme différente des autres. Application aux radars.
