Integrated electronic device for the transmission/reception of a radio frequency wave

An integrated electronic device, comprising:

• a waveguide having a first input/output and a second input/output, said waveguide configured to guide a radio frequency wave from the first input/output to the second input/output or from the second input/output to the first input/output;
• a carrier substrate including a patch antenna system;
• an electronic integrated circuit chip including a front face electrically connected to a metal level of the carrier substrate;
• an electrically insulating embedding material surrounding said electronic integrated circuit chip, the electrically insulating embedding material disposed between the patch antenna system and the first input/output of the waveguide, wherein the patch antenna system is at least in contact with said electrically insulating embedding material;
• wherein the electronic integrated circuit chip is configured to electrically cooperate with the patch antenna module for transmission by the patch antenna system of said radio frequency wave to the first input/output through the embedding material;
• and
• wherein the electronic integrated circuit chip is further configured to process an electrical signal from the patch antenna system in response to patch antenna system receipt of the radio frequency wave output by the first input/output via the embedding material.
