Component group for radio frequency transponder card with coil wound around outside of flat carrier provided with through bore containing semiconductor chip

摘要

The component group has a coil provided by a metal wire forming several radially and axially adjacent coil windings (6) and an associated semiconductor chip fitted in a through bore in a flat carrier (2). The coil is wound around the outside of the flat carrier, e.g. within a peripheral groove (7) arranged between the upper and lower surfaces of the flat carrier. An independent claim for a radio frquency transponder card is also included.
