A directional antenna, characterized in that it is constituted by a double helix or propeller made of a conductive material of wire, tape or tube, and fed at least by one of its ends, helices that are formed in such a way or provided with such additional means, and that by means of rotation about their longitudinal axis they are so arranged in space that their polarization sensitivity, normally circular or elliptical, is varied in a preponderantly linear polarization sensitivity; because the double helix is formed in such a way, and its two halves are arranged to each other in such a way, that it can be tuned to maximum gain in the direction of the longitudinal axis, and because the supply side of the propeller or of the The double helix is thus formed or provided with such additional means that for use in a free space it can be fed with a symmetrical line, while for its direct mounting on a conductive surface, it can be fed with an asymmetric line.
