Multibeam Antennas for Emerging Satellite and Terrestrial Applications

Giovanni Toso, IEEE AP-S Distinguished Lecturer, European Space Agency

Giovanni Toso (IEEE S’93, M’00, SM’07, FM‘23) received the Laurea Degree (cum laude), the Ph.D. and the Post Doctoral Fellowship from the University of Florence, Italy, in 1992, 1995 and 1999, respectively. During his PhD and Post Doc he spent more than one year as a Visiting Scientist at the Laboratoire d’Optique Electromagnetique de Marseille, France. In 1999, he was a Visiting Scientist with the University of California (UCLA) in Los Angeles. In 2000 received a scholarship from Alenia Spazio, Rome, Italy. In the same year he has been appointed Researcher at the Radio Astronomy Observatory of the Italian National Council of Research (CNR). Since 2000, he has been with the Antenna and Submillimeter Waves Section, European Space Agency (ESA), European Space Research and Technology Centre (ESTEC), Noordwijk, The Netherlands. He has been initiating several research and development activities on satellite antennas based on arrays, reflectarrays, discrete lenses, and reflectors. In particular, in the field of Onboard satellite antennas, he has been coordinating activities on multibeam antennas mainly for Telecom applications. In the field of Terminal antennas, he has been supporting the development of reconfigurable antennas with electronic, mechanical, and hybrid scanning; some of these antennas are now available as commercial products. He has promoted the development of the commercial software tool QUPES by TICRA, now used worldwide, for the analysis and design of periodic and quasi-periodic surfaces, such as reflectarrays, frequency selective surfaces, transmitarrays, and polarizers. Dr. Toso received, together with Prof. A. Skrivervik, the European School of Antennas (ESoA) Best Teacher Award in 2018. In 2014, he has been the Guest Editor, together with Dr. R. Mailloux, of the Special Issue on “Innovative Phased Array Antennas Based on Non-Regular Lattices and Overlapped Subarrays” published in the IEEE Transactions on Antennas and Propagation and, for the same society, has been an Associate Editor from 2013 to 2016. In 2018, he has been the Chairperson of the 39th ESA Antenna Workshop on “Multibeam and Reconfigurable Antennas”. Since 2010, together with Dr. P. Angeletti, he has been instructing short courses on Multibeam Antennas and Beamforming Networks during international conferences, such as IEEE Antennas and Propagation Society (APS), IEEE MTT International Microwave Symposium (IMS), IEEE International Conference on Wireless Technology and Systems (ICWITS), European Conference on Antennas and Propagation (EuCAP), and European Microwave Week (EuMW), that have been attended by more than 1100 participants. Together with Dr. P. Angeletti, he is the organizer of the EurAAP-ESoA Course on Active Antennas. Together with Dr. E. Gandini, he is also the organizer of the EurAAP-ESoA Course on Satellite Antennas, one of the most consolidated ESoA Course, attended so far by about 270 participants. From January 2023 Giovanni Toso has been elevated to IEEE Fellow grade for contributions to multibeam antenna developments for satellite applications. G. Toso is a Distinguished Lecturer of the IEEE Antennas and Propagation Society.
