| Zusammenfassung: | The present invention relates to radio engineering and is applicable to antenna feeder devices, mainly to compact antennas with enhanced broadbanding. An antenna comprises a spiral antenna made by conductors arranged in a single plane and formed into a bifilar helix. Two antenna elements are disposed in the same plane and coupled, opposite to each other, to the conductors at outer turns of the bifilar helix. The bifilar helix is a rectangular spiral made by line segments with right angles of the turns. Each of the antenna elements forms an isosceles trapezoid and is coupled to a termination point of a conductor at a vertex of the smaller base of the isosceles trapezoid. The bases of the isosceles trapezoids are parallel to the line segments of the bifilar helix. |
