Abstract
A radio-frequency antenna for a magnetic resonance system has a basic element with two end rings and a number of antenna rods, and a radio-frequency mirror. The end rings are arranged concentrically relative to an antenna axis can and are axially offset from one another. The antenna rods are arranged around the antenna axis and connect the end rings. The radio-frequency mirror is inductively coupled to the end rings and the antenna rods. It limits a magnetic resonance excitation signal emitted by the antenna and/or a magnetic resonance signal received by the antenna axially at one side.
