Directional Properties of Spatial Dipoles Arrays Located Above Perfectly Conducting Plane

Abstract

The fast active algorithms and software for numerical analysis of the radiation patterns and directive gains of 2D and 3D antenna arrays of the dipoles with axially separated amplitude-phase current distribution, located above a perfectly conducting (PEC) plane are developed. The analytical expressions obtained for the interference factors of the equidistant linear dipoles arrays located above a PEC plane along the axes of the Cartesian coordinate system (CCS) when the dipoles axes being parallel to CCS axes are used. Comparative numerical analysis of the directivity of antenna arrays of half-wave dipoles located at a distance of quarter wavelength above the screen depending on the distance between dipoles and their number is carried out.
