A local antenna device for transmitting magnetic resonance (MR) signals of a plurality of MR receiving antenna elements to an MR signal processing device is provided. The local antenna device includes a plurality of analog-to-digital converters for scanning the MR signals and converting the MR signals to digital MR data, and a plurality of transmitting antenna elements for wirelessly transmitting the digital MR data to the MR signal processing device by the emission of an electromagnetic field. The local antenna device includes a plurality of transmitting devices for triggering the transmitting antenna elements and a plurality of spacer elements that is arranged and embodied 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.
