Self-decoupled coil sensitivity to separation and loading. a Bench test setup to measure robustness to separation between two adjacent coils. b Bench test setup to measure robustness to loading. c Measured reflection coefficient (S11) of conventional and self-decoupled coils vs. coil separation (1 to 7 cm). d Measured normalized transmission coefficient (S21) of conventional and self-decoupled coils versus coil separation (1 to 7 cm). e Measured S11 of conventional overlapped and self-decoupled coils versus coil-to-phantom distances (1.5–7.5 cm). f Measured normalized S21 of conventional overlapped and self-decoupled coils vs. coil-to-phantom distances (1.5–7.5 cm). Compared to conventional coils, the self-decoupled coils had improved robustness to coil separation and similar robustness to loading
