A method for adjusting a field distribution of an antenna arrangement of a magnetic resonance system is provided. The symmetry of the field distribution may be impaired by positional inaccuracy of the antenna arrangement in the magnetic resonance system. The antenna arrangement comprises oscillating circuit antenna elements and switching elements. Each of the oscillating circuit antenna elements is assigned a respective switching element of the switching elements. A respective switching element is configured to couple the assigned oscillating circuit antenna element operatively to the antenna arrangement in dependence on a status of the respective switching element. During the method, symmetry information on the field distribution in the antenna arrangement is measured, and the switching elements are automatically adjusted using the measured symmetry information, such that the symmetry of the field distribution in the interior of the antenna arrangement is increased.
