Eloi Fresnel is a first‑year PhD student working on satellite antenna technologies.
With a dual background in engineering and entrepreneurship, he focuses on solutions that balance performance, cost, and real‑world constraints.
He is curious about space sovereignty, sustainable space infrastructure, and responsible use of space.
Endurance sports, especially triathlon, play a central role in his life.
Rethinking Satellite Antenna Design
Eloi’s doctoral research explores advanced phased‑array antenna architectures for space applications. His work challenges the assumption that high performance necessarily requires thousands of active elements.
His key insight is that smarter array architectures can achieve similar performance with far fewer electronics. This has major implications for cost, reliability, and sustainability in future satellite systems.
Balancing Theory and Reality
Educated in electronics and telecommunications engineering at INSA Rennes, with additional training in innovation and entrepreneurship at Rennes School of Business, Eloi is used to navigating between theory and application.
One of the biggest lessons of his PhD so far has been learning to embrace uncertainty. Elegant solutions are not always the most useful once implementation, integration, and cost are considered.
Curiosity About Space and Society
Beyond antenna design, Eloi is interested in larger questions around space sovereignty, sustainable infrastructure, and resilience in space systems.
He enjoys stepping outside his technical niche and discussing his work with people from entirely different fields, believing that the best ideas often emerge at intersections.
From Research to Impact
Although his research is already closely linked to industry, Eloi is keen to better understand how ideas move from the lab into concrete applications.
He wants to strengthen his ability to translate deep technical expertise into actionable solutions that matter in real contexts.
Energy, Balance, and Perspective
Sport plays a major role in how Eloi maintains balance and focus. Endurance training helps him push limits while staying grounded.
“Innovation is not just about better technology, but about making it usable, resilient, and meaningful.”
