An RF antenna or coil comprising a decoupling circuit including a parallel resonant trap circuit is disclosed for electromagnetically decoupling the RF antenna or coil when both RF antennas or coils are arranged in such proximity to each other that without a decoupling circuit couplings between both RF antennas or coils have to be expected which might lead to a decrease of the signal to noise ratio of received and/or transmitted RF signals or which couplings might lead other detrimental effects. Further, an RF transmit/receive antenna arrangement especially for an MR (magnetic resonance) imaging system or scanner is disclosed, wherein the RF transmit/receive antenna arrangement comprises an RF transmit antenna or coil which is preferably provided only for transmitting RF signals, and an RF receive antenna or coil which is preferably provided only for receiving MR signals (i.e. "dedicated" RF antennas or coils), wherein at least one of theses RF antennas or coils is provided with a decoupling circuit according to the invention.
