Abstract

Antenne filaire améliorée à large bande de fréquences Cette antenne comporte : un élément rayonnant (4) disposé dans un plan rayonnant (S) transversal à un axe (A) de l’antenne ; un plan réflecteur (8), qui est transversal à l’axe (A), le plan rayonnant étant situé à une hauteur prédéterminée (h0) au-dessus du plan réflecteur (8) ; et un substrat (6), interposé entre le plan rayonnant (S) et le plan réflecteur (8), et présentant une épaisseur constante. Cette antenne se caractérise par une permittivité électrique relative locale du substrat (6) qui est une fonction du rayon (r), c’est-à-dire de la distance à l’axe (A), et d’une hauteur (h), c’est-à-dire d’une distance au plan réflecteur (8), la permittivité électrique relative locale étant, à hauteur constante, croissante en fonction du rayon, et, à rayon constant, croissante en fonction de la hauteur au moins pour une portion du substrat (6) au voisinage du plan réflecteur (8).
