The device contains a flat card, a microcircuit, a dielectric substrate onto which the microcircuit is installed, and an antenna, which is made of an electrical conductor provided along the periphery of and in the plane of the flat card and connected to the microcircuit. The antenna is in the form of a frame, made of an electrical conductor, and a dielectric layer, provided within the electrical conductor, with a hollow space being formed within the frame. At least one partition is installed in the hollow space within the frame, forming through-openings which run transversely relative to the plane of the flat card. One end of the partition is connected to the dielectric layer of the frame. The electrical conductor of the antenna is made of a noble metal. |
