Abstract

Ce dispositif d'antenne (10) comporte un premier substrat plan (12) présentant au moins une face où sont formés au moins une antenne radioélectrique (20, 22), s'étendant dans une première portion rayonnante (16) du premier substrat (12), et des moyens électriquement conducteurs (24, 26, 28) de raccordement de l'antenne radioélectrique (20, 22) à un circuit électronique d'émission et/ou réception, ces moyens électriquement conducteurs s'étendant dans une deuxième portion (18) du premier substrat (12). Il comporte en outre un deuxième substrat plan (14) différent et sécant du premier, séparant la première portion rayonnante (16) du premier substrat (12), située dans un premier demi-espace par rapport à ce deuxième substrat (14), de la deuxième portion (18) du premier substrat (12), située dans un deuxième demi-espace par rapport à ce deuxième substrat (14). Le deuxième substrat (14) présente une face inférieure, orientée du côté du deuxième demi-espace, comportant une structure de métamatériau (38) à multiples éléments électriquement conducteurs (40) séparés électriquement les uns des autres sur cette face inférieure.
