Abstract

Dispositif (900) d’émission et/ou réception de signal radiofréquence, destiné à être intégré au sein d’un système de détection de geste dans un véhicule automobile, et comportant : - un circuit imprimé (930) ; - au moins une antenne planaire (910), dite antenne en T, comportant superposés une première surface métallique d’excitation et un premier plan de masse, l’un au moins parmi le premier plan de masse et la première surface métallique d’excitation présentant une région en forme de T , de sorte que le diagramme de rayonnement de l’antenne en T présente deux lobes latéraux de fort rayonnement, avantageusement situés dans le plan du circuit imprimé, et séparés par une zone centrale de faible rayonnement ; et - au moins une antenne planaire (920), dite antenne rectangulaire, comportant superposés une seconde surface métallique d’excitation et un second plan de masse, la seconde surface métallique d’excitation comportant une région rectangulaire ayant une forme générale de rectangle et configurée pour que le diagramme de rayonnement de l’antenne rectangulaire présente deux lobes latéraux de fort rayonnement, avantageusement situés dans un plan orthogonal au plan du circuit imprimé, et séparés par une zone centrale de faible rayonnement.
