We show, by Finite Elements Modelling, the tuning and matching feasibility of a highly coupled parallel transmission (PTx) array by means of two degrees of freedom (two capacitances values) and decouple them a posteriori. This approach could be useful to simplify the design of PTx arrays avoiding complex procedures to geometrically and/or electrically decouple the elements. The procedure is stable for small parameters changes and this suggests a possible experimental verification of the results.
