A receiver coil array for a magnetic resonance imaging system has multiple receiver coil loops that are decoupled from each the by a decoupling circuit that connects a pair of decoupling capacitors between any two of the receiver coil loops. One capacitor of each pair of decoupling capacitors has both ends grounded respectively through diodes of detuning circuits in the different receiver coil loops, and the other capacitor of each pair of decoupling capacitors has both ends grounded respectively through the tuning capacitors of different receiver coil loops. Alternatively the two decoupling capacitors in each pair have one end grounded through the diodes of respective detuning circuit, and the other end grounded through tuning capacitors of another said receiver coil loop.
