Abstract

Dans un système émettant des signaux à l'aide d'une antenne d'un magnétron destiné à des buts chauffage, un filtre quart d'onde pour le deuxième harmonique est plié de façon à réduire la longueur totale de l'ensemble. Eventuellement, un filtre peut être formé simultanément, pour le troisième harmonique ou pour des harmoniques supérieurs. Application : fours micro-ondes.
