Decoupling between neighboring current elements is essential in the design of parallel transmit arrays. In this work, the effect of various impedance matching schemes on the active rung design was investigated in terms of the correlation between the driven current amplitude and the induced current suppression. Experimental results showed a trade-off between the two parameters in the single ended active rung and suggest a need to explore multiple MOSFET configurations.
