An examination subject arranged in an examination volume of a magnetic resonance system can be excited to magnetic resonance by an RF transmission antenna. The RF transmission antenna is fashioned as a resonant structure that surrounds a central axis of the magnetic resonance system running within the examination volume. The resonance structure has inner edges proceeding around the central axis on its inner side facing the central axis, which inner edges form a capacitively-bridged annular gap extending parallel to the central axis. The RF transmission antenna is embedded into the gradient coil, such that the gradient coil at least radially outwardly and axially surrounds the RF transmission antenna), and the inner edges of the RF transmission antenna are connected in an electrically-conductive manner with inner sides of the gradient coil to the central axis. They are arranged radially inwardly (viewed from the annular gap) and axially completely cover the annular gap as well as axially at least partially cover the inner sides of the gradient coil.
