Abstract: A multiple antenna system comprises at least two dipole-type radiators with first and second radiator elements, respectively, which are arranged at a distance from a reflector arrangement. A phase shifter arrangement with a phase shifter adjustment device is connected to the first and second radiator elements to adjust the phase relationships between the first radiator elements and between the second radiator elements. A decoupling arrangement is coupled to a decoupling adjustment device. The decoupling adjustment device is mechanically coupled to the phase shifter adjustment device, so that when the phase shifter adjustment device is moved, the decoupling arrangement: is changeable in its length, width and/or shape; or is changeable in its position, whereby the change of position is accelerated or only partially synchronized with the adjusting movement of the phase-shifting device; or is changeable in its position, wherein the decoupling arrangement is arranged within at least one of the radiators.

Abstract: A phase shifter module arrangement comprises a phase shifter with a plurality of emitter connections and a central point connection. A matching network is provided. The matching network comprises a signal connection and a phase shifter connection. A separating device is provided which is electrically conductive and is arranged between the phase shifter and the matching network. The separating device has a first side on which the phase shifter is arranged and a second side on which the matching network is arranged. A connection opening connects the first side to the second side. The phase shifter connection of the matching network is connected electrically via the connection opening of the separating device to the central point connection of the phase shifter.

Abstract: Positioned above the actual pointer head of the pointer-shaped feed element, through which the centre axis or swivel axis passes, is an additional capacitor coupling device or coupling disc that is arranged at a distance from said pointer head and is electrically isolated therefrom. This additional coupling device or disc is separated from the electrically conductive pointer head by a disc-shaped insulator which is inserted therebetween.

Abstract: A differential phase shifter assembly with n striplines positioned concentrically with one another, on the opposite stripline ends of which connecting points for connecting lines leading to radiators are provided, where n is a natural integer greater than or equal to 2. A feeding and/or tapping device is pivotable about a central and/or pivot axis, and is therefore pivotable over the plurality of striplines while establishing a primary capacitive coupling. A central feed serves to feed the feeding and/or tapping device. At least one to n?1 secondary capacitive couplings are additionally provided. The one or more secondary capacitive couplings are provided on the side of the feeding and/or tapping assembly facing the primary capacitive coupling. For the at least one additional secondary capacitive coupling, at least one additional branched feeding and/or tapping device is provided, which together with the feeding and/or tapping device is pivotable about the central and/or pivot axis.

Abstract: An impedance converter device comprises an electrically conductive external conductor with one or more connection locations for electrical lines, an electrically conductive internal conductor with one or more connection locations for electrical lines, and also a dielectric arranged between external conductor and internal conductor. The external conductor comprises a base area bounded by one or more side walls thereby forming an external conductor housing with an internal space and an opening opposite the base area. The internal conductor is arranged in the internal space. The internal conductor and the external conductor are insulated from one another by the dielectric. The internal conductor comprises at least one cutoff bar-type section with a cutoff bar bottom and at least one wall which extends from the bottom in the direction of the opening of the external conductor housing.
