Fast Simulation of Antenna Array with Parameters Variation

In this work, we propose a hybrid method to fast solve the optimization of array located on the PEC carrier inside the dielectric radome with parameters variation. By constructing a reusable low-rank reduced-order model (ROM) for complex carriers, a large number of repeated calculations are reduced and the analysis cost of the antenna array is reduced when the position of array is modified. By combining of frequency-and material-independent response (FMIR), the sweep of media parameters and frequency can be accelerated. The tangential equivalence principle algorithm (T -EPA) is applied to solve the array problem, and the number of unknowns on the antenna array is transferred to the equivalent surface, which is easier for the iterative convergence of the matrix equation. Therefore, the number of unknowns and the analysis cost of the antenna array can be reducecd.
