Abstract: An electronic circuit board comprising an assembly of a printed circuit board comprises a first face receiving at least one electronic component, and a heat sink, the printed circuit board and the heat sink stacked in a stacking direction, the heat sink fixed to the printed circuit board on a second face opposite the first face, the heat sink comprising a base, in the form of a plate, and reliefs extending from a flat surface of the base, the reliefs intended to increase the contact surface between the heat sink and a flow of air relative to the contact surface between the base and the flow of air, the base interposed between the printed circuit board and the reliefs in the stacking direction, the heat sink fixed directly to the printed circuit board by gluing only and wherein the heat sink is of a single piece.

Abstract: The invention relates to a wire antenna adapted to operate in at least one predetermined frequency band, comprising a plurality of superimposed layers, comprising at least one radiating element placed on a support layer, wherein the support layer is placed on a spacer substrate, and wherein the spacer substrate is placed on a reflector plane comprising at least one resistive layer between the support layer of the radiating element(s) and the substrate spacer, while the resistive layer comprises at least two sets of nested resistive patterns. This antenna is such that the sets of resistive patterns have resistance values gradually varying between a central antenna point and an outer edge of the antenna, in order to achieve a resistance gradient.
