Abstract

An improved antenna array, having at least two groups of individual antenna elements comprising a dipole square and/or patch antenna elements with a square antenna element structure. Individual antenna element arranged at least horizontally offset with respect to one another are provided for each of the two polarizations which are at right angles to one another. At least two additional antenna elements are horizontally offset with respect to one another, and/or at least two pairs of vertically aligned individual antenna elements, which are arranged with a horizontal offset with respect to one another, are provided for each of the two orthogonal polarizations. The individual antenna elements which are in each case arranged with a horizontal offset with respect to one another and are aligned parallel to one another are fed with different phase angles as a function of the depression angle.
