Abstract (en)
[origin: WO2018142051A1] The electronic card with printed circuit (1) comprises at least one antenna with slots (AT) including a cavity (15) and a metal conductive layer (17) covering the cavity and having a plurality of slots (S17). The slots form openings in the metal conductive layer. In accordance with the invention, the cavity is formed, by removal of material, in the thickness of the printed circuit. The cavity also comprises a metallisation layer (16) on the walls and the metal conductive layer is formed in a plate attached on the electronic card with printed circuit and closes the cavity.
