Abstract
A feed or output-coupling apparatus for coaxial lines has a spur line which is short-circuited at the end. In order, at least in the case of a single coaxial line, to allow a broadband connection of the inner conductor to the outer conductor, or at least in the case of a multiple coaxial line, to allow a corresponding short-circuiting connection between the inner conductor and outer conductor at least in a narrowband form, at least two interleaved coaxial spur lines are provided. Each spur line is short-circuited at their respective ends via a short-circuit with their lengths being dimensioned such that the associated short-circuit at the feed and connecting point is transformed to an open circuit, depending on the respectively appropriate frequency band range.
