Abstract (en)
[origin: EP0512876A1] An antenna producing, under circular polarisation, a radiation pattern which is axisymmetric about an axis (1) and exhibits a radiation minimum in the direction of this axis, characterised in that it comprises: - a reflective conductive surface (2), essentially axisymmetric about the axis, - a straight conductive wire (6) extending axially from a first end (7), situated level with this conductive surface and insulated from it, to a second end (8), this conductive wire being connected at its first end to a supply line (4, 5), and - a plurality of radiating arms (9, 10), each including a first portion (9) extending essentially in a radial plane (11) from the second end of the conductive wire, this first portion being, at its near end, connected electrically and directly to the conductive wire and being, at its far end, prolonged by a second portion (10) in the shape of a curvilinear wire typically being inscribed in a sphere centred on the said second end and whose general direction is inclined with respect to the said radial plane. <IMAGE>
