Abstract: Filter arrangement comprising an inner electric conductor comprising at least one inner conductor segment, an outer electric conductor at least partly surrounding the inner conductor, at least one dielectric element and at least one coil spring. The at least one dielectric element is arranged sandwiched between at least one inner conductor segment and the outer conductor to form a capacitance between the outer conductor and the inner conductor segment. The at least one coil spring is arranged inside said outer conductor to force the inner conductor segment and the at least one dielectric element against the outer conductor. The at least one coil spring is made from an electrically conducting material to form an inductance and is electrically connected with the inner conductor segment. An antenna feeding network and a multi-radiator antenna comprising such a filter arrangement is also provided.

Abstract: A reflector for a multi-radiator antenna which comprises electrically conducting reflector parts and one or more connector device. At least two reflector parts are each provided with at least one connecting portion. At least one connector device is adapted to provide an electrical interconnection between at least two of the reflector parts. At least one connector device comprises a metallic film and one or more holding elements. The metallic film is adapted to be arranged in abutment with connecting portions of the at least two of the reflector parts to achieve the electrical interconnection. At least one of the holding elements has at least one holding portion adapted to connect to a connecting portion of a reflector part with said metallic film sandwiched therebetween. The electrical interconnection is indirect by means of a dielectric coating or layer arranged on the metallic film and/or on the connecting portions, or by means of a dielectric film arranged between the metallic film and the connecting portions.
