摘要：
An electrically conductive transmission line for transmitting RF signals, in particular for transmitting MR signals between a transmission and/or receiving coil and a transmitting and/or receiving unit, by which separate known matching networks can be avoided or reduced. A transmission line is proposed comprising a plurality of lead segments coupled by transformers having a transformer impedance ZL placed between two neighboring lead segments, wherein for power matching of the two transformers placed at opposite ends of a lead segment, the lead segment has a lead segment impedance Z0 or a dielectric constant ∈r and wherein the lead segment has a short length l. Thus, the lead segments themselves provide the matching of the transformers, and separate matching circuits are no longer needed.
