Abstract :
The hybrid volume-surface integral equation approach is implemented to calculate the radiation and scattering by large microstrip arrays on curved substrate and ground plane. The multilevel fast multipole algorithm is applied to reduce the memory and CPU requirements for solving the matrix equation. Numerical results for input impedances of single patch and the scattering pattern for an array are presented.
