Created in December 2022, Planexus is a spin-off of IETR, a CNRS-affiliated public research laboratory.
We are located in Rennes, France, just 1h30 from Paris by TGV train.
Products
Our ambition is to design and propose a new generation of antenna systems for mobile SATCOM terminals on the move (SOTM), at K/Ka band, for LEO, MEO and GEO orbit satellites.
Technology
Our technologies are as innovative as they are disruptive.
This allows us to develop SATCOM antenna solutions that are more compact, lighter, particularly efficient and at a lower cost.
Service
Planexus is also offering high-performance antenna design and consulting services for companies.
We help you to integrate off-the-shelf Planexus’s antennas or we can design a full custom antenna for your device.
Our highly skilled experts are here to help you.
OUR BOARD
Dr. Khalid SAYEGRIH Chairman
Expert in RF Signal processing
PhD of Engineering in digital signal processing.
In 1992, he created the company ST2E in the field of digital radio communications for military applications.
In 2002, Khalid started a second company ADVANTEN in the field of specific digital radio solutions for hostile environments.
Within his companies, Khalid intervened in a transversal way on all aspects: General management, HR, Technical, Industrial, commercial, banking and finance, academic partnerships, setting up and running French and EU collaborative projects.
Khalid joins the Planexus project by bringing all his experiences as a startup creator and developer.
Dr. Lionel Algarra CEO
Expert in management and business development
Lionel is a graduate of HEC Paris (2009) and holds degrees in engineering and a PhD in chemistry. In 2000, he joined the innovation consulting firm Erdyn, becoming a partner in 2004 and Director in 2010.
Lionel has extensive experience in the general management of SMEs and B2B business development. With a strong dual expertise in business and technology, he has supported the creation and growth of more than 50 tech startups, providing advice in areas such as business strategy, marketing, roadmapping, partnerships, and technology transfer.
Joining in 2024, Lionel is the CEO of Planexus.
Dr. Mauro Ettorre Technical Advisor
Expert in multibeam SATCOM antennas
Mauro Ettorre obtained his master’s degree and Ph.D. in electrical engineering from the University of Siena in 2008. Between 2010 and 2023, he served as a senior CNRS researcher at the IETR Laboratory.
Currently, he is a full professor at Michigan State University, USA. During his tenure at IETR, Mauro led the multi-beam antenna research activities within the joint laboratory between IETR and Thales Alenia Space. Recognized worldwide for his expertise in millimeter-wave antennas for space applications, he was named an IEEE Fellow for his ontributions to large antenna arrays utilizing quasi-optical beam formers.
Mauro acts as technical advisor for Planexus on Satcom antennas.
Pr. Ronan Sauleau Scientific Advisor
Expert in planar antenna arrays in millimeter band
Ronan received the aggregation of electrical engineering in 1996, then the doctorate from the French University of Rennes in 1999.
He is currently an exceptional class professor at the University of Rennes. His research focuses on antennas, planar antenna arrays in millimeter band (especially in Ka band) and associated beamformers. His research work has resulted in the filing of 26 patents. In 2008, Ronan received the French CNRS bronze medal, the CNRS silver medal in 2020 and the Antenna EurAAP Award in 2021. He is IEEE Fellow.
