Abstract
In this paper, a time domain method is introduced for analyzing microstrip antennas having thin slots. The present method is based on a resolution of Maxwelľs. equtions using the finite difffreence time domain method. A particular investigation has been made for taking thin slots into account, this avoids a prohibitive grid to represent the slots. Two kinds of antennas have been analyzed by this method: the slot antennas and the radiatins patch fed by a line through a slot.
Résumé
Cet article présente une méthode ďanalyse théorique desantennes imprimées comportant, entre autres, des fentes minces. La technique développee est basée sur une résolution dans le domaine temporel des équations de Maxwell par différences finies. Le traitement des fentes fait ľobjet ďune étude particulière qui évite une discrétisation à ľintérieur de ces dernières permettant ainsi un gain important en place mémoire et en temps de calcul. Deux types de structures sont analysées par la méthode: les antennes à fentes et les plaques rayonnantes alimentées par ľintermédiaire ďune fente.
