Abstract: An electronic device includes an electronic integrated circuit chip assembled on a first region of a substrate. A radiation element of an antenna is mounted to the substrate in a manner where it is separated from the substrate by a second layer of a second dielectric material, and i\s further offset with respect to the first region of the substrate so that the radiation element does not cover the electronic integrated circuit chip. A first coating layer of a first coating material covers at least a surface of the electronic integrated circuit chip facing away from the substrate further covers a surface of the radiation element facing away from the substrate.

Abstract: A support substrate supports an electronic chip. An encapsulation coating on the support substrate coats the electronic chip. The encapsulation coating includes a trench surrounding the electronic chip. A heat sink is mounted to the encapsulation coating above the electronic chip. The heat sink is fixed to the encapsulation coating by an adhesive material and a thermal interface material layer is present between the electronic chip and the heat sink. The trench is positioned between the thermal interface material layer and the adhesive material.
