ISAW 2021 : Talk by Dr Giovanni Toso on 'Active Antennas with Reduced Complexity'

Описание: There is today a high interest in developing Active Antennas that guarantee superior performance in terms of flexibility and reconfigurability. This trend is evident not only when considering advanced satellite payloads but also for ground professional antennas considered for 5G and MIMO applications. Unfortunately, Active Antennas tend to be extremely complex and expensive. Their complexity grows roughly as the product of the number of beams multiplied the number of radiating elements. When
considering applications requiring more than 1000 radiating elements and more than 1000 beams, the complexity is extremely critical.

Giovanni Toso 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. Since 2000 he is with the Antenna and Submillimeter Waves Section of the European Space Agency, ESA ESTEC, Noordwijk, The Netherlands. He has been initiating and contributing to several R&D activities on satellite antennas based on arrays, reflectarrays, discrete lenses and reflectors. He holds more than 20 international patents. Since 2010, together with Dr. P. Angeletti, he has been instructing short courses on Multibeam Antennas and Beamforming Networks during international conferences (IEEE APS, IEEE IMS, IEEE IWCS, EUCAP, EuMW) that have been attended by more than 850 participants. In 2018 he received, together with Prof. A. Skrivervik the 2018 ESoA Best Teacher Award out of 101 teachers.
