General information
Organisation
The French Alternative Energies and Atomic Energy Commission (CEA) is a key player in research, development and innovation in four main areas :
• defence and security,
• nuclear energy (fission and fusion),
• technological research for industry,
• fundamental research in the physical sciences and life sciences.
Drawing on its widely acknowledged expertise, and thanks to its 16000 technicians, engineers, researchers and staff, the CEA actively participates in collaborative projects with a large number of academic and industrial partners.
The CEA is established in ten centers spread throughout France

Job title
Reduction of high environmental impact material in 6G antennas
Subject
How to reduce the amount of high-impact materials used in a 6G base station antenna network?
Host laboratory:
• The CEA-Leti Antennas and Propagation Laboratory continues to innovate in the field of next-generation radio frequency telecom infrastructures. It brings together around thirty experts and cutting-edge computing and experimentation facilities.
Internship context:
• As part of the European SUSTAIN-6G project, CEA-Leti has focused on the environmental and social impacts of future 6G technology. In this context, we wish to go further by guiding antenna network designers in their choice of materials and components to minimize environmental and social impacts from the very beginning of the product life cycle.
Contract duration (months)
5 - 6 months
Job description
The mission:
• You will start by analysing the technologies of these antennas in order to measure the quantity of certain so-called conflict metals (gold, tin, etc.) contained in these antennas and to understand their functions.
• You will evaluate material alternatives (e.g., discrete RF component vs. printed function), operational or functional alternatives with equal or sufficient performance, and provide recommendations to guide the choice of materials and architecture during the design step of this type of antennas. You will ensure to identify any potential impact transfers potentially induced by such alternatives.
• Depending on the progress of your internship, you will expand your field of study to other materials and components, notably soluble PCB substrates. You will analyse the trade-off between performance (dielectric and conductive losses) and impact transfer on a simplified 6G antenna array mock-up.
