Description

one

The invention relates to radio engineering, and can be used in antenna systems with rotating polarization, and is an improvement of the invention according to the author. No. 1075343.

The purpose of the invention is to improve the ellipticity coefficient in the hemispherical viewing sector and to expand the matching band.

The drawing shows a structural scheme of a turiket antenna.

The turnstile antenna contains a symmetrical vibrator with shoulders 1 and 2, two pairs of additional vibrators 3-6, each connected to a corresponding metal conductor 7-10, placed parallel to the shoulders 1 and 2 of the symmetric vibrator, and forming with them directional responders, excitation unit 11, screen 12 and additional conductors 13-16, which are made in the form of a wire or in the form of a continuous triangular metal plate.

The antenna works as follows.

{The shoulders 1 and 2 of the symmetric vibrator are excited by the node 11, excited, while on the metal conductors 7-10, currents similar to the currents in the directional branches are induced.

Dividing the power in half between the opto-polar components of the circular polarization is provided
