Planar diffraction radiation antenna with combined grating

Abstract

This paper describes a new method proposed for obtaining a special form radiation pattern. The main idea of this method is to use a combination of straight and incline diffraction gratings in a planar diffraction radiation antenna. A comparison of radiation characteristics of straight and inclined gratings was made. The radiation pattern of antenna with a combined grating confirms the correctness of the chosen approach. The obtained results are an essential complement to known properties of antennas and justify their applicability in different complexes of surface surveillance.
