The invention relates to a continuous strip comprising a fibrous structure including continuous or discontinuous fiber and a resin which is tacky at a temperature between ambient temperature and 300°C, said strip having a dielectric constant of between 2 and 7 and a dielectric tangent of between 1.10-4 and 3.10-2 at 20°C and at 9.375 GHz. The above-mentioned fibrous structure is sufficiently stiff so that the strip has a stiffness of between 5 and 30° at a temperature at which the resin is tacky, the stiffness of the strip being measured on the basis of a 15cm-long rectilinear segment, 5 cm of which is placed on the edge of a horizontal surface and the remaining unsupported 10 cm collapsing to form an angle with the horizontal that characterizes the stiffness of the strip. The strip of the invention is particularly suitable for the production of dielectric composite materials, such as radomes, using fiber positioning technologies.
