Résumé

L’article présente, une contribution à l’étude des antennes diélectriques microruban uniformes à ondes de fuite. Les caractéristiques de rayonnement sont obtenues après calcul de l’exposant linéique de propagation complexe par la méthode de résonance transverse combinée à la méthode de Galerkin, en utilisant un modèle de guide d’onde à murs magnétiques. On en déduit une formulation intégrale rigoureuse par application de l’opérateur admittance, où un schéma équivalent est systématiquement adopté pour introduire le concept de fonctions de test. Pour des raisons pratiques, seul l’harmonique d’espace n = - 1 est considéré et sa variation en fonction des dimensions de l’antenne est présentée. Plusieurs exemples sont traités et quelques-uns des résultats sont comparés à ceux obtenus par une analyse spectrale [7,8].

Abstract

In this paper, a contribution to uniform micro-strip leaky-wave antenna is presented. All its radiating characteristics are obtained, once complex propagation constant is calculated by transverse resonance combined to Galerkin method, when applying wave-guide model with magnetic walls. Then an integral formulation by application admittance operator is set where systematically an equivalent network introduces the concept of test functions. For practical reasons, only space harmonic n = - 1 is considered and its variation versus antenna dimensions is illustrated. Several examples are treated and some of the results are compared to those obtained by a spectral analysis [7,8].
