ABSTRACT:
An antenna arrangement having at least a first and a second conductor section (2, 2a, 8) that are connected to one another via a capacitor arrangement (6, 6a, 6b). During operation, the first conductor section (2, 2a) exhibit an alternating first potential and the second conductor section (8) exhibits an alternating second, opposite potential with respect to a reference potential. A shielding against electrical fields is arranged between the antenna conductor arrangement and the imaging volume (12). The shielding (16) has no electrical connection to the reference potential. The shielding (16) has a first overlap region (18) with the first conductor section (2, 2a) and has a second overlap region (20) with the second conductor section (8). The relationship of the two overlap regions (18, 20) to one another is selected such that the potential of the shielding (16) assumes reference potential during operation.
