Abstract

The analysis of conformal microstrip antennas printed on arbitrary curved surfaces is of importance as the shape of these surfaces directly influences the radioelectric performance of these antennas. This article proposes to simulate these structures using the finite difference time domain (fdtd) method developed in curvilinear coordinates. This method will be illustrated by several examples of conformal structures.

Résumé

L’étude d’antennes microrubans conformées imprimés sur des surfaces non planes quelconques s’avère d’autant plus indispensable que la forme de la surface influence directement les performances radioélectriques de l’antenne. Cet article propose de simuler ces structures par la méthode des différences finies dans le domaine temporel développée en coordonnées curvilignes. La méthode sera illustrée sur différents exemples de structures conformées.
