An improved antenna array is distinguished inter alia by the following features: each of at least two antenna columns contains at least one supplementary antenna element, the at least two supplementary antenna elements are arranged such that the centers of the at least two supplementary antenna elements are arranged with a horizontal lateral spacing (b) that is smaller than the lateral spacing (a) between the centers of the antenna element groups or of the antenna elements in the two antenna columns, the wideband antenna elements in a respective antenna column are fed jointly together with the at least one supplementary antenna element, and a distribution network is provided for the at least one antenna element group with the at least one associated antenna element with an associated filter function (F) for the at least one associated supplementary antenna element, which radiate in a higher frequency subband than the wideband antenna elements. |
