An improved antenna control apparatus as well as an associated antenna and a method which has been improved in this context are distinguished by the following features: the control apparatus has control electronics, the control apparatus furthermore has an electric motor, an antenna control apparatus can be retrofitted outside the protective cover for the mobile radio antennas, or else as a preferably complete unit underneath this protective cover.

Control apparatus for changing a downtilt angle for antennas, in particular for a mobile radio antenna for a base station, as well as an associated mobile radio antenna and a method for changing the downtilt angle

An improved antenna array includes at least two vertically running gaps. There are overall at least two and preferably at least three radiators or radiator groups offset to one another in the vertical direction in one gap and preferably in all gaps. In at least one gap, the arrangement is such that the radiators or radiator groups in this at least one gap except for at least one radiator or at least one radiator group are jointly supplied. This at least one radiator or at least one radiator group is supplied jointly with the radiators or radiator groups of an adjacent gap.

Two-dimensional antenna array

An improved antenna control apparatus as well as an associated antenna and a method which has been improved in this context are distinguished by the following features:

CONTROL DEVICE FOR ADJUSTING A DIFFERENT SLOPE ANGLE, ESPECIALLY OF A MOBILE RADIO ANTENNA ASSOCIATED WITH A BASE STATION, AND CORRESPONDING ANTENNA AND CORRESPONDING METHOD FOR MODIFYING THE SLOPE ANGLE

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.
