A radio frequency coil for transmitting or receiving signals at a magnetic resonance frequency includes an arrangement of substantially parallel rungs (70, 70′, 70″) and one or more generally annular strip-type end-rings (78, 78′, 78″, 80) disposed generally transverse to the parallel rungs and connected with the rungs. Each generally annular strip-type end-ring includes at least two conductor layers (82, 82′, 82″, 84, 84′, 84″, 86, 88) separated by a dielectric layer (72, 72a, 72b). A radio frequency shield (34) substantially surrounds the arrangement of substantially parallel rungs (70, 70′, 70″). At least one of the conductor layers of each end-ring is connected with the radio frequency shield. |
