The demand about invivo multi-nuclear MRI/MRS has increased according to introduction of higher tesla MR system. The development of the dual frequencies RF coil array keeps pace with this interest. At the overlay of both the proton and second-nucleus frequencies coil loops, inductive coupling between coils has resolved to retain proton sensitivity and coil tuning stability by LLC and LC tank circuit. However, they cause another mutual coupling issue between the circuits and coil loops. Therefore, we introduce a simpler and more efficient decoupling method than LLC and LC tank circuit in this study.
