Abstract

Une antenne multi-bande (100) comprend une plaque métallique de base (10) qui est destinée à servir de plan de masse électrique, et une pluralité de plaquettes métalliques (1-3) qui sont superposées au-dessus de la plaque métallique de base. Toutes les plaquettes métalliques sont connectées en parallèle entre un fil d’alimentation en signal (11A) et la plaque métallique de base. De préférence, les plaquettes métalliques ont des surfaces respectives qui augmentent avec la distance de chaque plaquette métallique à la plaque métallique de base. L’antenne présente autant de valeurs différentes de fréquence de résonance que le nombre des plaquettes.Figure d’abrégé : Figure 1a
