Abstract:

This paper presents the nonparametric optimization of a Q-band horn antenna for CubeSat satellite applications. 
The nonparametric optimization software Tosca allows a vast design space to be explored without the constraints imposed by predefined parameters. Instead, allowing the geometry and material properties of the antenna to evolve dynamically, adapting to the desired performance criteria.
Key considerations in the optimization process include gain maximization, sidelobe and axial ratio minimization in the Q-band spectrum. 
The results of this research highlight the possibilities offered by the Tosca nonparametric optimizer for the design and development of advanced satellite communication systems. By pushing the boundaries of antenna optimization beyond parametric limits, this approach helps improve the efficiency and reliability of Q-band horn antennas in satellite communication applications.

About the Speaker:

Nicholas Sesto Gorella is a Mechanical Engineer and Antenna Designer for PICOSATS s.r.l. In his role as a Mechanical Engineer, Nicholas is responsible for designing, simulating, and testing the housing for Ka and Ku transceiver boards produced by PICOSATS, overseeing the product through to satellite integration. As an antenna designer, Nicholas designs, simulates, and tests double reflector, horn, patch array, and slot array antennas covering X, Ku, K, Ka, Q, and V bands. 
Nicholas graduated from the University of Trieste in 2017 with a bachelor's degree in industrial engineering and, in 2020, with a master's degree in mechanical engineering. His interest in additive manufacturing has led him to gain experience with FDM, DIW, SLS, SLA, and L-PBF techniques. His research activities have led to his participation in various projects funded by the European Space Agency.
