FIELD: physics.
SUBSTANCE: flat current-conducting antenna component is in form of isosceles triangles with angles at their common vertex, respectively, Θ1°≈127° and height and Θ2°≈117°, distances h2=0.85*h1, h3=0.85 *h2 and so on, are measured from the base of the triangles to the vertex of the antenna component; parallel to the bases of the triangles in accordance with the measured distances h, slits of width S1 and S2=0.85S1 are respectively cut from left to right and from right to left up to the vertex of the antenna component; the ready antenna component with the slits is then folded into a cone by bringing together its equal sides with a wedge-like gap between them; the axis of the gap is directed orthogonal to the plane of shield of the counterweight for an end-fed antenna; the axes of the gaps of two identical cones are directed along a straight line for a centre-fed antenna.
EFFECT: providing ultrabandwidth of linearly polarised antennae by cutting off conduction current on conductors of end-fed and centre-fed linearly polarised antennae.
