Résumé
Dans cet article, on présente la résolution du problème d’antenne diélectrique à ondes de fuite à motif métallique quelconque. Ceci est suggéré, dans un but de montrer l’influence de la forme du motif métallique, de sa surface transverse sur les caractéristiques de rayonnement et de comparer ensuite les avantages et les inconvénients des formes non régulières à ceux de la forme régulière classique (ruban rectangulaire). Un autre défi qui trouve son application dans plusieurs domaines est la possibilité de conformer le diagramme de rayonnement et d’améliorer les performances des caractéristiques de rayonnement.
Abstract
In this article, the resolution of a dielectric leaky-wave antenna problem of arbitrary metallic strips is presented. This is suggested with an aim of highlighting the influence of the form of the metallic parts, and their transverse surface on the radiating characteristics and to compare the advantages and disadvantages of the non regular forms with those of regular form (rectangular strip). Another challenge which finds its application in several fields, is the possibility of conforming the radiating pattern and performing the characteristics of radiation.
