Claim:
1. Method of making a compact control module of a high frequency antenna for a magnetic resonance imaging device comprising a plurality M of control elements and a plurality N of radiating elements, said plurality N of radiating elements being greater than said plurality M of control elements, said control module being represented by a control matrix {tilde over (P)}, where {tilde over (P)} is a matrix approximately equal to a control matrix P to control said plurality N of radiating elements using said plurality M of control elements; said method comprising: decomposing the approximate control matrix {tilde over (P)} into a product of two matrices H×L; the first matrix L with dimensions M×M being capable of transforming a plurality M of signals V producing said matrix H with a number of stages less than a number of stages necessary for implementation of the control matrix P, said stages being implemented by coupling means, phase shifting means and permutation means; using said matrix L by software means starting from implementation of said matrix H determined during the producing.
