ELECTRONIC DEVICE INCLUDING AN ELECTRONIC CHIP AND AN ANTENNA

A carrier substrate includes an integrated network of electrical connections extending from a front face to a back face. An electromagnetic antenna is located on the front face of the carrier substrate and is connected to the integrated network. An electronic chip is mounted over the front face of the carrier substrate, and connected to the integrated network, at a location offset from the antenna. An encapsulation layer encapsulates the electronic chip. The encapsulation layer includes, recessed with respect to its front surface, a local void that is located laterally away from the electronic chip and extends over a zone that at least partly covers the location of the electromagnetic antenna.
