Cet article suggère un nouveau type d'hybride à 180 degrés à 3 dB, constitué d'une cavité cylindrique et de quatre guides d'ondes rectangulaires à plan E couplés radialement à celle-ci, et montre que de bonnes propriétés hybrides sont obtenues en modifiant les positions des quatre entrées/sorties. guides d'ondes et rayon de la cavité cylindrique qui sont déterminés par la distribution de champ du TE111 mode résonant. De plus, une méthode d'élargissement de la bande passante avec des étapes d'impédance supplémentaires est décrite. Le présent hybride se caractérise par une structure simple et est donc utile pour les applications aux fréquences d'ondes millimétriques et aux systèmes micro-ondes de haute puissance. Une vérification expérimentale est également présentée.

Abstract: This paper suggests a new type of 180-degree 3 dB hybrid, which consists of a cylindrical cavity and four E-plane rectangular waveguides radially coupled with it, and shows that good hybrid properties are realized by modifying the positions of the four input/output waveguides and the radius of the cylindrical cavity that are determined by the field distribution of the TE111 resonant mode. Moreover, a method of broadening the bandwidth with additional impedance steps is described. The present hybrid is marked by simple structure, and hence is useful for applications at millimeter wave frequencies and to high-power microwave systems. Experimental verification is additionally shown.
