Résumé

En utilisant la méthode de raccordement modal, associée à ľapproche dans le domaine spectral, on caractérise des discontinuités uniaxiales élémentaires et complexes en technologie microruban suspendu. Des schémas équivalents décrivent les discontinuités élémentaires et peuvent servir ultérieurement dans une base de données en vue de ľutilisation en cao hyperfréquence. On a conçu et réalisé un coupleur et des résonateurs fonctionnant vers 30 GHz en technologie microruban suspendu sur du Duroïd. Des vérifications expérimentales valident les calculs. En utilisant la technique des équations intégrales avec résolution par la méthode des moments, on caractérise des jonctions multiaxiales dans la même technologie. La méthode est appliquée à des jonctions de forme complexe tel qu’un coude, un té ou un méandre. Pour cette méthode, on observe aussi un bon accord entre la théorie et ľexpérience.

Abstract

Simple and complex suspended stripline uniaxial discontinuities are precisely characterized using the modal analysis combined with the spectral domain approach. Frequency dependent equivalent circuits for the studied discontinuities are derived. They can be used as data base for microwave cad programs. A directional coupler and different resonators are realized in this suspended stripline technology using the results of this study. Experimental performance of these components validates our theoretical results. An integral equations technique solved by the method of moments is used to characterize suspended stripline multiaxial junctions. Examples of the results are given for a bend, a T or a meander. A good agreement is observed between theoretical results and experimental ones.
