La technologie à bande ultra large (UWB) repose sur les nouveaux concepts de signaux à impulsions très courtes. Cette technologie est un bon candidat pour les réseaux de nouvelle génération (4G), mais elle nécessite une nouvelle approche de la conception des antennes afin d'obtenir les caractéristiques UWB. Ce travail analyse la conception d'une antenne à bande ultra large (UWB) à alimentation par ligne microbande et présente des simulations d'antennes UWB en mode transitoire utilisées pour vérifier les améliorations des paramètres de l'antenne. L'antenne a été conçue sur un substrat FR4 avec une constante diélectrique ǫr = 4,4, une tangente de perte (tan δ)=0,02. L'antenne a été optimisée pour présenter les caractéristiques UWB dans la gamme de fréquences 3,1 GHz-12 GHz. Le diagramme de rayonnement de cette antenne est presque omnidirectionnel dans le plan H et bidirectionnel dans le plan E. L'effet de divers paramètres de conception sur la conception a également été analysé à l'aide du simulateur CAD Feko 6.1 utilisant la méthode MoM. Les résultats simulés sont en bon accord avec les normes FCC, montrant un VSWR
