Abstract

An improved antenna array has at least two columns running vertically. At least in one column and preferably in all columns, at least two radiators or radiator groups are arranged together in a vertical direction. For at least one column having at least two radiators or radiator groups vertically offset from one another, at least one additional radiator group is provided, which is fed commonly with the radiators or radiator groups provided in this column. The additionally provided at least one radiator or radiator group for the column is arranged horizontally offset to the other radiators or radiator groups provided in the column.
