Transformer or capacitor is often required to electromagnetically decouple the gapped loops, non-adjacent loops, or microstrip resonators in RF coil arrays when conventional coil overlapping is not applicable. In this abstract, we analyze the general L/C decoupling circuits and suggest the use of inductor for decoupling at high fields. Based on the circuit analysis, a new inductive decoupling method is proposed for designing microstrip arrays at high magnetic fields.
