Antenna for Telecommunication Systems

The results of the development of antennas with circular polarization are presented. Distinctive features of antennas are: non-directional radiation pattern in the azimuthal plane and a narrow radiation pattern in the elevation plane when the maximum of the emission of the horizon line is shifted by an angle from 0° to 30°. The antenna ensures the emission of circular polarized waves with the ellipticity in 0.98 within the main lobe of antenna pattern. The ellipticity does not decreased below 0.6 in a wide range of elevation angles and 360 grad in azimuthal plane.
