Abstract
A microwave coupling element for coupling an input conductor with an output conductor exhibiting a predetermined wave propagation resistance includes a coupling portion interposed between the input and output conductors and including two parallel strip conductors that are galvanically uncoupled from one another. The strip conductors are spaced from each other by a predetermined distance and each has a predetermined width, at least one of the predetermined width and the predetermined distance being up to twice as large as that which would correspond to a minimum mismatch with the input and output connectors. The resulting mismatch is compensated for by at least one transformation connector exhibiting a wave propagation resistance smaller than the predetermined wave propagation resistance.
