Abstract
An electronic device includes an integrated circuit linked to a coil antenna forming at least a spiral having opposite ends connected to the integrated circuit, and a plate support for supporting the integrated circuit and the coil antenna. The plate support is conductive and open ring shaped, wherein the internal circumference of the ring is concentric to the spiral. The opening of the ring is obtained by a cut through the plate support. The coil antenna is fastened to and isolated from the plate support through an insulating material. The cut and the plate support are filled by the same insulating material.
