Abstract

La présente invention concerne une antenne 5G et son unité de rayonnement. L'unité de rayonnement comprend deux groupes de dipôles orthogonaux polarisés, chaque groupe des dipôles comprenant deux bras de rayonnement disposés à l'opposé l'un de l'autre à un intervalle, et les bras de rayonnement étant chacun pourvus d'une première branche d'extension et d'une seconde branche d'extension agencées à un intervalle. L'unité de rayonnement peut étendre une bande de fréquence de travail et présente de bonnes performances de rayonnement, et par conséquent l'antenne 5G à l'aide de l'unité de rayonnement présente une bonne performance de rayonnement.
