Abstract:
1. An antenna arrangement for a magnetic resonance system, comprising: a plurality of antenna rods arranged substantially regularly around an antenna axis, said antenna rods proceeding substantially axially relative to said antenna axis; each antenna rod having two opposite rod ends and a rod center between the two opposite rod ends; connection elements proceeding substantially tangential to said antenna axis that electrically-conductively connect the rod ends of each antenna rod with rod ends of at least one of said antenna rods immediately adjacent thereto; said antenna rods being nearer-symmetrical relative to a plane of symmetry proceeding perpendicular to said antenna axis; each point of each antenna rod defining, with said antenna axis, a radial direction, and said rod center defining, with said antenna axis, a reference direction, and each radial direction forming, with said reference direction, a tangential angle; and for each antenna rod, said tangential angle being a non-constant function of an axial spacing of the respective point from said rod center.
