Abstract
An antenna arrangement for a magnetic resonance device has a first antenna group, which includes at least one antenna element, and a second antenna group separated from the first antenna group, which likewise includes at least one antenna element. The antenna groups have respective cooperating coupler antenna parts that are fashioned and/or arranged such that, given a specific adjacent arrangement of the antenna groups with respect to one another, the coupler antenna parts form, by inductive coupling, a common boundary antenna element of the two antenna groups, which is inductively decoupled from the further antenna elements within the appertaining antenna groups. A corresponding method for coupling two antenna groups separated from one another employs such an antenna arrangement.
