Abstract
The optimization of a Gaussian optic lens antenna design is considered using a previously exposed model. After discussing the global task, results with a few varying geometrical parameters are presented which study their effects on certain radiation characteristics such as the half pattern aperture angles 3 dB and 10 dB below the axial maximum, the sidelobes level or the beam efficiency. Finally, we are able to conclude on the complexity and the difficulty of optimizing such an antenna.
Résumé
L’optimisation de la conception d’une antenne asso-ciant un cornet rainuré à une lentille diélectrique est envisagée à i’aide d’un modèle précédemment explicité. Après avoir posé le problème, des investigations sont faites sur un nombre réduit de paramètres géométriques en étudiant leur influence sur quelques caractéristiques du diagramme de rayonnement tels que son ouverture à 3 et à 10 dB, le niveau des lobes secondaries et l’efficacité de faisceau. On conclut enfin sur la nature du problème de l’optimisation et sur sa difficulté de mise en œuvre.
