  • Antenna of the helix type having radiating strands with a sinusoidal pattern and associated manufacturing process
    Patent number: 8259030
    Abstract: The invention relates to an antenna of the helix type, comprising a plurality of radiating strands wound in a helix in an axisymmetric form (15), characterized in that each radiating strand is made up of at least one reference pattern (MR1, MR2, MR3) defined by an analytic function defined in a reference frame, the axis of the abscissae of which is the director axis of the radiating strands and is a periodic function of (I) or (II) and Ak correspond respectively to the frequency and to the amplitude of the sinusoid of index k.

  • HELIX ANTENNA
    Publication number: 20100156752
    Abstract: 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).
