  • Patent number: 5173713
    Abstract: The invention relates to a radioelectric communication antenna with a very wide band width and a low standing wave ratio. The antenna includes at least two linear elements in combination that are substantially the same length (L). The median axis (42) of the antenna forms a predetermined angle (A), the apex of which, when the angle (A) differs from 0.degree., is a point (P) close to the bases (40) which are adapted to be electrically connected to a transmission line (2). Each linear element includes at least one electrically resistive means (5) disposed between two predetermined portions of each element, and at least one electrically inductive means (6), which in turn is disposed substantially between the base (40) of each element (4) and the transmission line (2). The inductive means (6) have selected inductances (L1, L2, L3) which differ from one linear element to another.
