Abstract

Une antenne (100) pour émettre un rayonnement à partir d'au moins une onde électromagnétique progressive qui se propage le long d'un trajet de guidage, est conçue pour réduire une réflexion susceptible de se produire pour l'onde progressive en extrémité du trajet de guidage. Pour cela, le trajet de guidage comporte au moins une partie en forme de segment de spirale (11, 12), qui est connectée à une autre partie du trajet de guidage en forme de boucle (13). Un gain sur le coefficient de réflexion de l'antenne peut être obtenu de cette façon, qui est effectif notamment à proximité d'une limite fréquentielle inférieure d'une bande de transmission de l'antenne.
