Un coupleur hybride à 2 plans et guides d'ondes avec deux bandes de fonctionnement est proposé. La forme en coupe transversale de la région couplée à l'intérieur du coupleur proposé est conçue avec une méthode de tri géométrique arbitraire bidimensionnelle. Les simulations du coupleur hybride proposé ont une bande passante fractionnaire (FBW) de 2.17 % au centre de 24.99 GHz et au centre de 28.28 GHz une FBW de 6.13 %. Le coupleur proposé est analysé par la méthode hybride d'éléments finis d'appariement de modes, et le résultat final est obtenu à l'aide d'un algorithme génétique. Le résultat analysé du couplage pour les principaux modes dans la région couplée est présenté. Le résultat de la conception est confirmé par des mesures.

Abstract: A waveguide 2-plane hybrid coupler with two operating bands is proposed. The cross-sectional shape of the coupled region inside the proposed coupler is designed with a two-dimensional arbitrary geometry sorting method. Simulations of the proposed hybrid coupler has a fractional bandwidth (FBW) of 2.17% at the center of 24.99GHz, and at the center of 28.28GHz an FBW of 6.13%. The proposed coupler is analyzed by the mode-matching finite-element hybrid method, and the final result is obtained using a genetic algorithm. The analyzed result of the coupling for the main modes in the coupled region is presented. The design result is confirmed by measurements.
