About the Author

Roberto Vincenti Gatti – Senior RF/Microwave Consultant – Phased Array Specialist

Roberto Vincenti Gatti received the Laurea degree summa cum laude from the University of Perugia, Italy, in 2000, and the Ph.D. degree from the same University in 2007. Since 2007 he is Assistant Professor at the University of Perugia where he currently teaches the courses of Antennas and Microwave Systems for Aerospace. He has produced more than 110 publications and presentations in international conferences and he is holder of two international patents.

Along the years he headed several industrial and research projects attaining a profound know-how and experience in the area of phased array antennas and RF passive microwave systems.

His main expertise are:

• Analysis and design of slotted waveguide arrays for radar and communication systems (mono-pulse radars, flared slotted waveguide arrays, beam steering slotted waveguide arrays, etc.).
• Phased arrays (WG aperture, patch, Vivaldi, etc.) and BFNs in waveguide (WG, ridge WG, coaxial line, etc.) and printed technology (microstrip, stripline, CPW, square coax., etc.).
• Active arrays: architectures and design techniques.
• Electronic beam steering reflectarray antennas.
• Reflector antennas.
• Microwave components and devices.

SWAN™ is the result of more than twenty years of experience on antenna arrays, a unique tool developed in response to numerous requests and growing needs of antenna designers working on slotted waveguide arrays, not fully satisfied by the today available commercial software products.
