Abstract:
1. An impedance converter device for converting impedances in antenna arrangements, comprising: an electrically conductive external conductor with at least one connection location, an electrically conductive internal conductor with at least another connection location, a dielectric disposed between the external conductor and internal conductor, the external conductor comprising a base area bounded by at least one side wall thereby forming an external conductor housing defining therein an internal space and an opening opposite the base area; the internal conductor being disposed in the internal space defined within the external conductor, the internal conductor and the external conductor being insulated from one another by the dielectric; the internal conductor comprising at least one section having outwardly extending bars with a bottom and at least one wall which extends outwardly from the bottom in the direction of the opening of the external conductor housing, wherein the at least one connection location and the at least another connection location are disposed opposite to one another, the impedance converter extends in a longitudinal direction between the opposite connection locations, and the bottom of said section with outwardly extending bars is assigned at least two walls which extend outwardly in the direction of the opening of the external conductor housing from edges of the bottom.
