Claim:
1. A local antenna device for transmitting magnetic resonance (MR) signals of a plurality of MR receiving antenna elements to an MR signal processing device, the local antenna device comprising: a plurality of analog-to-digital converters operable to scan the MR signals and convert the MR signals to digital MR data; a plurality of transmitting antenna elements operable to wirelessly transmit the digital MR data to the MR signal processing device by emission of an electromagnetic field; a plurality of transmitting devices operable to trigger the plurality of transmitting antenna elements; a substrate that supports the plurality of transmitting antenna elements; and a plurality of spacer elements arranged on the local antenna device such that at least a defined minimum emission spacing is produced between the plurality of transmitting antenna elements and articles adjoining the local antenna device in at least one direction of a principal axis of emission of the electromagnetic field, wherein the plurality of transmitting antenna elements are enclosed by the substrate and at least one spacer element of the plurality of spacer elements.
