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.
