Abstract
Réseau antennaire à rayonnement directif L’invention concerne un réseau antennaire à rayonnement directif adapté à fonctionner dans au moins une bande de fréquences prédéterminée, qui comprend au moins une paire d’antennes métalliques (8,10) formée d’une première antenne métallique et d’une deuxième antenne métallique, la deuxième antenne métallique étant positionnée en rotation séquentielle d’un angle de rotation prédéterminé par rapport à la première antenne métallique, un circuit de charge (6), chaque antenne métallique étant connectée audit circuit de charge, et une antenne monopôle (12), ayant une position centrale dans le réseau antennaire, connectée audit circuit de charge (6). Les antennes métalliques et l’antenne monopôle sont agencées sur un plan de masse (4) et couplées, le circuit de charge (6) étant paramétré pour réaliser un rayonnement dans lequel l’antenne monopôle (12) a une contribution destructive d’un mode de rayonnement transverse magnétique, permettant d’obtenir un rayonnement, par ladite au moins une paire d’antennes métalliques, de polarisation circulaire choisie. Figure pour l'abrégé : Figure 3
