Abstract

The invention relates to a mechanical support device (10) for at least one sensor plate, for example an antenna element (18) in a device for transmitting and/or receiving electromagnetic high-frequency signals. According to the invention, the support device (10) is configured as a coil form (24, 26) of at least one winding (32, 32′, 32″; 34, 34′, 34″; 36, 36′, 36″) in an inductive sensor. In addition, the invention relates to a measuring device comprising multiple sensors, in particular a locating device (80) for detecting objects that are enclosed in a medium, said measuring device having at least one support device (10) of this type.
