Abstract (en)
[origin: FR2826186A1] The antenna comprises a generator and two parallel metallic surfaces, which may be formed be etching a metallic layers on a substrate. One of the metallic surfaces (120) is divided into two concentric parts comprising a central part (122) and a strip (124) surrounding the central part and connected to generator terminals. This provides multi-function operation for the antenna. The antenna comprises a generator and at least two parallel metallic surfaces, superimposed one on top of the other. At least one of the metallic surfaces (120) is divided into two concentric parts comprising a central part (122) and a strip (124) surrounding the central part. The two parts are connected by means of one or several conducting strips to first and second generator terminals. The connections (150,160) linking the metallic strips to the generator may stand perpendicular to the plane of the metallic surfaces. The two metallic layers (120, 140) may be formed be etching a metallic layer on either side of a substrate, or by use of controlled contours within the substrate.
