Abstract: 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.

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.

Abstract: An antenna comprises at least two or more radiators such as, especially dual-polarized radiators, and at least one additional passive conducting decoupling elements. The decoupling element, in its longest direction of extension, or at least one component of the decoupling element, with its longest direction of extension, extends in the propagation direction of the electromagnetic waves and/or perpendicular to the plane of the reflector.

Abstract: A dual-polarized antenna system is provided for transmitting or receiving electromagnetic waves. The antenna system has at least one cruciform radiating element module that is aligned using dipoles or in the form of a patch radiating element, at angles of +45° and −45° with respect to vertical. The antenna system further has a conductive reflector arranged in the back of the at least one radiating element module. Two conductive side wall sections are provided on each side of the at least one radiating element and are disposed vertically. At least one slot is provided in each side wall section at the level of the radiating element module and extend in parallel to the reflector plane.

Abstract: An antenna array for simultaneous reception or for simultaneous transmission of electromagnetic waves having two linear, orthogonal polarizations has a decoupling device (17) between adjacent radiating element modules (1). This decoupling device is provided between two radiating element modules (1) which are adjacent in the attachment direction (21). The improvement is for a decoupling structural element (17) to be provided between two adjacent radiating element modules (1), which decoupling structural element (17) extends at least with its longitudinal component in the attachment direction (21), this longitudinal component having a length which is greater than or equal to 25% of the radiating element module separation (25) between the centers or bases (23) of the corresponding adjacent radiating element modules (1).

Abstract: In order to create a directional antenna, in particular a dipole antenna, that is improved over the prior art, can be produced and is designed comparatively simply, and furthermore has further improved electrical properties, it is provided that the symmetrizer (7) is made from the material of the reflector (5), in that the symmetrizer (7) is cut from the remaining material of the reflector wall (5), except for a connecting segment (11), by suitable cuts and/or stamping operations, and preferably in the region of the immediate connecting point (11) with the remaining material of the reflector wall (5) is bent out relative to the plane of the reflector wall.
