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. y = A 0 sin ( 2 π x T ) + ∑ k = 1 ∞ A k sin ( 2 π σ k x T ) ( I ) 2 π σ k 1 T ( II )
