Abstract

Ce dispositif d'antenne (10) comporte au moins deux antennes radioélectriques (20, 22), dont les ports de raccordement électrique (20A, 20B, 22A, 22B) sont disposés sur un même substrat (12), et des moyens (24, 26, 28) électriquement conducteurs de raccordement des ports (20A, 20B, 22A, 22B) desdites au moins deux antennes radioélectriques (20, 22) à un circuit électronique d'émission et/ou réception. Chaque antenne radioélectrique (20, 22) est conformée pour présenter une désadaptation d'impédance avec le circuit électronique d'émission et/ou réception telle que son coefficient de réflexion en entrée ou en sortie soit supérieur à une valeur seuil prédéterminée en l'absence de toute réadaptation d'impédance. Mais les moyens électriquement conducteurs de raccordement (24, 26, 28) comportent des composants électriques capacitifs, inductifs et/ou résistifs (40, 42, 46) de réadaptation d'impédance avec le circuit électronique d'émission et/ou réception, disposés pour ramener ledit coefficient de réflexion à une valeur inférieure à la valeur seuil prédéterminée.
