Nelson J. G. Fonseca (M’06, SM’09) was born in Ovar, Portugal, in 1979. He received the M.Eng. degree from Ecole Nationale Supérieure d’Electrotechnique, Electronique, Informatique, Hydraulique et Télécommunications (ENSEEIHT), Toulouse, France, in 2003, the M.Sc. degree from the Ecole Polytechnique de Montreal, Quebec, Canada, also in 2003, and the PhD degree from Institut National Polytechnique de Toulouse – Université de Toulouse, France, in 2010, all in electrical engineering.
He worked as an Antenna Engineer successively with the Department of Antenna Studies, Alcatel Alénia Space, Toulouse, France (now Thalès Alénia Space), and with the Antennas Section, French Space Agency (CNES), Toulouse, France, where he completed his Ph.D. degree in parallel to his professional activities. In 2009, he joined the Antenna and Sub-Millimetre Wave Section, European Space Agency (ESA), Noordwijk, The Netherlands. His current research interests include multiple beam antennas for space missions, beam-former theory and design, ground terminal antennas and novel manufacturing techniques. He has authored or co-authored more than 200 papers in peer-reviewed journals and conferences. He contributed to 22 technical innovations, protected by over 40 patents issued or pending.
Dr. Fonseca is serving or served as a TPC member in several conferences. He also served as the Chair of the 38th ESA Antenna workshop on Innovative Antenna Systems and Technologies for Future Space Missions, October 2017, and as the Co-Chair of the 2018 IET Loughborough Antennas & Propagation conference (LAPC 2018). He is serving or served as a technical reviewer for over 20 journals and magazines, including the IEEE Transactions on Antennas and Propagation (TAP) and the IEEE Transactions on Microwave Theory and Techniques (TMTT). He is serving as an Associate Editor for the IET Microwave, Antennas and Propagation journal. He is a board member of the European School of Antennas (ESoA) since January 2019 and is actively involved in various courses related to space antennas and ground segment antennas. He received several prizes and awards, including the Best Young Engineer Paper Award at the 29th ESA Workshop on Antennas in 2007 as well as ESA Technical Improvement Awards in 2015 and 2017. He was the recipient of the IEEE Antennas and Propagation Society Commendation Certificate recognizing the exceptional performance of a reviewer for the IEEE Transactions on Antennas and Propagation in 2016.
