Abstract (en)
[origin: WO2008142099A1] The invention relates to a helix antenna comprising a plurality of radiating elements wound helically in an axisymmetric shape (15), characterized in that each radiating element comprises a repetition of the same pattern, which is defined by an at least second-order fractal (F1, F1' F2, F2', F3, F3', F4, F5).
