Jonas Flygare (Senior Member, IEEE) was born in Möndal, Sweden, in 1988. He received the B.Sc. and M.Sc. degrees in engineering physics and the Ph.D. degree in radio and space science from the Onsala Space Observatory, Chalmers University of Technology, Gothenburg, Sweden, in 2016 and 2022, respectively. In 2012, he was a Test Technician in semiconductor research and development with CBRITE, Inc., Goleta, CA, USA, where he was developing the thin-film-transistor technology for next-generation flat screens. In 2014, he was with the Department of Electrical Engineering, Chalmers University of Technology, working with gap-waveguide technology. From 2014 to 2016, he was a Project Researcher with the Onsala Space Observatory, where he designed the feed antenna for the Square Kilometer Array (SKA) Band 1. In 2020, he was invited as a Visiting Student Researcher at the California Institute of Technology (Caltech), Pasadena, CA, USA, where he was working with wideband feed development for the Deep Synoptic Array (DSA). He continued this work as a Post-doctoral Scholar Research Associate in radio astronomy instrumentation from 2022 to 2025 at Caltech.

He is currently a Staff Research Engineer in radio astronomy instrumentation with Caltech at Owens Valley Radio Observatory (OVRO), leading the feed design for the DSA project. His main research interests include the design and system characterization of ultrawideband antennas, reflector feeds, and receivers for radio astronomy and space geodesy. He has been involved in several international collaborations with design contributions to radio astronomy projects, such as SKA, DSA, the Allen Telescope Array (ATA), and European Very Long Baseline Interferometry Network (EVN).

Dr. Flygare is an Early Career Member of USNC-URSI Commission J (Radio Astronomy). He received the TICRA Travel Grant from the IEEE APS/URSI, Boston, MA, USA, in 2018. He received the award of Alumnus of the Year – Rising Star 2025 from his alma mater Chalmers University of Technology, Sweden for his academic career and his contributions to the development of future radio astronomy.
