The mobile radio antenna comprises a plurality of radiating elements and an antenna array module, which comprises at least a first housing module. The first housing module comprises a first receiving space and a second receiving space, which are separated from each other by at least one partition. A first phase shifter arrangement is situated in the first receiving space. A first duplex filter assembly is situated in the second receiving space. The at least one partition comprises a first opening, wherein a common terminal of the first duplex filter assembly is electrically or electromagnetically connected to a common terminal of the first phase shifter arrangement through the first opening. Furthermore, an antenna-side terminal of the first phase shifter arrangement is electrically connected directly or indirectly to a first terminal of at least one radiating element.

Abstract: A high-frequency filter with a coaxial design has at least one resonator with a first inner conductor and an outer conductor housing. The outer conductor housing comprises a housing base, a housing cover which is arranged at a distance from the housing base, and a peripheral housing wall between the housing base and the housing cover. The first inner conductor is galvanically connected to the housing base and extends axially from the housing base in the direction of the housing cover. The resonator comprises a second internal conductor which is galvanically connected to the housing cover and extends axially from the housing cover in the direction of the housing base. The first and/or second inner conductor has an inner conductor bore, and a tuning element is arranged in one inner conductor bore in a thread-free axially movable manner. The tuning element is arranged in a sleeve or bushing and optionally or in addition thereto has an enlarged elastic region.

Abstract: A coaxial filter having a frame construction comprises at least one filter frame, which consists of an electrically conductive medium and comprises a receiving space. A cover arrangement closes the receiving space on all sides. At least one first resonator internal conductor is arranged in the receiving space. The at least one first resonator internal conductor is galvanically connected to a face of the at least one electrically conductive filter frame, and extends therefrom in the direction of another, in particular opposing face of the electrically conductive filter frame, and ends at a distance from the opposing face of the electrically conductive filter frame and/or is galvanically separated from the opposing face of the electrically conductive filter frame.

Abstract: An improved high-frequency filter has an adjustment or sliding device for adjusting the coupler bandwidth. The adjustment or sliding device is attached to at least one coupling element. The coupling element is associated with a coupler opening relating to a resonator. The coupling element is related to an associated coupler opening arranged in the resonator such that a means of adjustment and thus the coupling element is adjustable between two extreme settings through adjustment of the adjustment or sliding device in which the coupling element is fully or partially slid into the coupler opening or fully or partially slid out of the coupler opening or is moved or positioned away from the coupler opening.

The difference between the thread pitches or the thread pitch angles between the external thread of the thread-like tuning element and the internal thread of the thread receiver is more than 0.5%, and preferably 1% to 5%.

Abstract: An improved HF coupler or HF power splitter comprises four connection lines arranged on the same side of the substrate. Two coupling zones are formed on the substrate on two opposite sides; the second coupling zone is connected to the associated connection lines arranged on the side of the substrate opposing the coupling zone, by means of two via holes in an electroplated manner. The capacitors provided at the beginning and at each end of each coupling zone are respectively embodied as interdigital capacitors; and the capacitors are respectively coupled to earth.
