Die Ultrabreitbandtechnologie (UWB) basiert auf neuen Konzepten f�r sehr kurze Impulssignale. Diese Technologie eignet sich gut f�r Netzwerke der n�chsten Generation (4G), erfordert jedoch einen neuen Ansatz beim Antennendesign, um die UWB-Eigenschaften zu erreichen. Diese Arbeit analysiert das Design einer rechteckig geschnittenen Ultrabreitbandantenne (UWB) mit Mikrostreifen-Leitungszuf�hrung und pr�sentiert UWB-Antennensimulationen im transienten Modus, die zur �berpr�fung der Verbesserungen der Antennenparameter verwendet werden. Die Antenne wurde auf einem FR4-Substrat mit einer Dielektrizit�tskonstante ǫr = 4,4 und einem Verlustfaktor (tan δ) = 0,02 entworfen. Die Antenne wurde so optimiert, dass sie UWB-Eigenschaften im Frequenzbereich von 3,1 GHz bis 12 GHz aufweist. Das Strahlungsmuster dieser Antenne ist in der H-Ebene nahezu omnidirektional und in der E-Ebene bidirektional. Die Auswirkungen verschiedener Designparameter auf das Design wurden ebenfalls mit dem CAD-Simulator Feko 6.1 unter Verwendung von MoM analysiert. Die Simulationsergebnisse stimmen gut mit den FCC-Standards �berein und zeigen einen VSWR
