Abstract

L'invention se rapporte à une antenne radioélec-trique à très large bande et à faible rapport d'amplitudes de tension. Elle est caractérisée en ce qu'elle comprend au moins deux éléments linéaires qui, en combinaison, d'une part, sont sensiblement de même longueur et forment avec l'axe médian de l'antenne un angle prédéterminé dont le sommet est, lorsque l'angle diffère de zéro degré, un point voisin de celles dites bases de leurs extrémités, à savoir celles qui sont électriquement reliées à la ligne de trans-mission, et d'autre part, comportent chacun au moins un dispositif électriquement résistant interposé entre deux fractions prédéterminées de chaque élément, et au moins un dispositif électriquement inductif quant à lui interposé
sensiblement entre la base de chaque élément et la ligne de transmission, ces moyens inductifs ayant des valeurs d'inductance choisies qui sont différentes d'un élément linéaire à un autre. La présente invention peut être appliquée à l'industrie du matériel électrique de transmission. The invention relates to a radio antenna very wide band with low amplitude ratio Of voltage. It is characterized in that it includes at minus two linear elements which, in combination, of a share, are substantially the same length and form with the median axis of the antenna a predetermined angle whose vertex is, when the angle differs from zero degrees, a point neighbor of those called bases of their ends, namely those that are electrically connected to the line of trans-mission, and on the other hand, each have at least one electrically resistant device interposed between two predetermined fractions of each element, and at least one electrically inductive device meanwhile interposed substantially between the base of each element and the line of transmission, these inductive means having values selected inductors that are different from an element linear to another. The present invention can be applied to the electrical equipment industry from transmission.
