Abstract
The structure (10) has a cavity arrangement (30) completely surrounded by a metallic support structure material and comprising a main surface (30-1) lying opposite to an adjacent outer side (10-1) of the structure. A transponder (20) is arranged in the arrangement. Symmetric metallic material projections (40, 50, 60) extend from the main surface into an inner volume of the arrangement. The projections are formed to partially obtain homogeneous alignment of read-magnetic field (M'1) when an outer read magnetic field (M1) for the transponder lies in the inner volume of the arrangement. The transponder is designed as a passive, contactless readable radio frequency identification (RFID) glass transponder.
