AbstractA new decoupling technique which takes advantage of shielding for coil array design is proposed. A ground plane is used to reduce mutual inductance by reducing the effective coupling loop area of circuits; in addition, a "screen track" is placed between adjacent coils to minimize magnetic interferences. This technique requires no modification of circuit and doesnít cause loss of flexibility of coil geometry. Simulation and experiments show that a ground plane beneath surface coils can reduce mutual coupling by 10-20dB, and a "screen track" can further provide a 2-8dB more isolation.
