Analysis and Design of Large Array Antennas Using a Fast Direct Solver

This paper presents the application of TICRA’s recent full-wave analysis advancements for antenna arrays, with a particular emphasis on the use of the Fast Direct Solver (FDS). We showcase the effectiveness of this method through real-world examples, including a 10×10 spline horn array, a 218 circular horn array, and a 25×25 microstrip patch array. The results demonstrate that the FDS-based approach offers significant improvements in efficiency and memory usage compared to traditional methods.
