摘要：
The electronic card with printed circuit comprises at least one diffraction structure (DS) having a cavity (15) and a diffraction plate (17). In accordance with the invention, the diffraction structure is incorporated in the thickness of the electronic card with printed circuit, the cavity being formed, by removal of material, in the thickness of the electronic card with printed circuit and the diffraction plate being formed in a plate which is arranged on the electronic card with printed circuit and closes the cavity.
