| 摘要 |
The present invention concerns an integrated circuit structure (1) formed in a substrate (2) and including at least one integrated circuit element (3, 4), an antenna coil (5) capable of transmitting and/or receiving data, and associated with said integrated circuit element(s) (3, 4); and a metal protective ring (20) situated at the periphery of the integrated circuit structure (1). The present invention is characterised in that said protective ring (20) comprises at least one ohmic interruption, so that it does not form a closed circuit on itself. The integrated circuit structure (1) according to the invention is improved in that the operation of the antenna coil (5) is made insensitive to the presence of the protective ring (20).
