Abstract
A semiconductor device includes a substrate, for example made of silicon, and layers, deposited on this substrate. Within at least one of these layers a radio signal transmission/reception antenna is formed. Located between the antenna and the substrate, a screen for collecting induced currents between this antenna and this substrate is formed within at least one of the layers. The screen includes at least one main branch connected to a fixed potential, for example a ground reference, and a plurality of secondary branches connected to the main branch at one of their extremities. The collector screen accordingly presents a tree-like structure.
