| Vivaldi antenna array, including 144 Vivaldi elements, is used as the feed antenna for a parabolic antenna. The feed structure is embedded between the Vivaldi elements, and the vias are connected a pair of Vivaldi elements. Since the small gap in the Vivaldi element and thin neck of the feed structure require the small cell sizes, this project is 732 x 732 x 365 non-uniform cells. GEMS box system is used to simulate this problem. The simulation took about 5 hours and 21 minutes for the 25,000 time steps. |
