Abstract

Antenne radiofréquence planaire à polarisation circulaire La présente invention concerne une antenne radiofréquence (10) comportant un réseau antennaire (12) fonctionnant à une longueur d’onde et comprenant : un dipôle alimenté (14A) relié en un point d’accès (15) à un transmetteur radiofréquence générant ou recevant une onde à la longueur d’onde,au moins un dipôle couplé (14C1, 14C2, 14C3) relié en un point d’accès à une charge (Z1, Z2, Z3) respective, le dipôle alimenté (14A) et chaque dipôle couplé (14C1, 14C2, 14C3,) comportant deux brins s’étendant depuis le point d’accès (15), les points d’accès (15) étant agencés pour former un polygone, le premier brin d’un dipôle (14) s’étendant le long du deuxième brin d’un dipôle (14) voisin à une distance inférieure au dixième de la longueur d’onde.
