Although transformer, capacitive and inductive decoupling techniques have been widely used in transmit or receive coil arrays, a comparative analysis of their tolerances to load variances were not reported. In this study full wave electromagnetic simulations with realistic coil models are used to understand the robustness of each decoupling method to the variations in size and electrical properties of the loading object.
