Abstract
A moment method procedure is used to solve the integral equations describing rectangular dual patch microstrip antennas. After checking the accuracy of the procedure by comparing calculated with measured results, it is used to analyse theoretically the effect of the top patch, especially the variation of the impedance curve and the gain of the configuration with two parameters, the distance between the two patches and the size of the top patch. Finally, a first attempt is made to outline a technique for the determination of these two parameters in order to obtain a maximum bandwidth.
Résumé
La méthode des moments est utilisée pour résoudre l’équation intégrale d’une antenne microruban rectangulaire à plaques empilées. Après le contrôle de la précision de la procédure par une comparaison des résultats calculés et des résultats mesurés, la procédure est utilisée pour analyser théoriquement l’effet de la plaque supérieure, en particulier la variation de l’impédance et du gain de la configuration avec deux paramètres, la distance entre les deux plaques et la dimension de la plaque supérieure. Finalement, un premier effort est fait pour construire une technique pour déterminer la valeur des deux paramètres afin d’obtenir la bande la plus large.
