Abstract
An RF coil is proposed for use as an RF antenna for a MR imaging system, for transmitting RF excitation signals and for receiving MR relaxation signals, The RF coil of the invention includes an array of patches (1) which are capacitively coupled with each other. The array of patches forms a resonant surface on which surface currents can be resonantly excited for generating at least one field modus.
