FIELD: radio engineering, communications.SUBSTANCE: method to manufacture a spiral antenna, in which flat tape straight or zigzag conductors of an antenna spiral are made according to the number of spiral turns from a flexible dielectric material with a low tangent of a loss angle according to the number of conductors, on the surface of each dielectric substrate the tape conductors are rigidly fixed, besides, substrates with attached conductors are collected in the packet by means of their application onto each other with different sides: a substrate with a conductor - a substrate without a conductor, and so that the conductors are opposite to each other, one end of the flat packet is rigidly fixed, the fixed end of the substrates packet is applied onto the side surface of a solid cylindrical object, the diameter of which is equal to two initial radii of the spiral, and the length is more than the width of substrates, a packet of substrates and conductors is screwed onto this object, the manufactured cylindrical packet of substrates and conductors is rigidly fixed, from the rigid cylindrical packet of substrates a cylindrical object is withdrawn, afterwards the inner ends of spiral conductors are connected galvanically with appropriate conductors of a feeder or a matching transformer.EFFECT: reduced diameter of an antenna aperture and its increased amplification ratio.2 cl, 4 dwg |
