| 摘要 |
The present invention relates to an electrically conductive transmission line for transmitting RF signals, in particular for transmitting MR signals between a transmission and/or receiving coil (11) and a transmitting and/or receiving unit (12), by which separate known matching networks can be avoided or reduced. A transmission line is proposed comprising a plurality of lead segments (31) coupled only by transformers (32, 33) having a transformer impedance ZL placed between two neighbouring lead segments, wherein for power matching of the two transformers (32, 33) placed at opposite ends of a lead segment (31) said lead segment (31) has a low lead segment impedance Zo and/or a high dielectric constant &egr;r and wherein said lead segment (31) has a short length 1. Thus, the lead segments themselves provide the matching of the transformers, and separate matching circuits are no longer needed.
