要旨:
Decoupling is crucial for constructing transceiver phased arrays. Interaction between the elements can severely compromise both transmission performance and SNR. Previously described decoupling techniques have focused on eliminating the reactance of the mutual impedance, which can limit the obtainable S12 to -10 dB due to residual mutual resistance. Recently we introduced a double-tuned 7T 31P/1H transceiver array. Due to frequency dependence of the mutual inductance two separate decoupling circuits required between each array element. Double-tuning of the decoupling coils can significantly simplify the design. In this work we described a novel inductive decoupling technique, which addresses both these issues.
