Abstract :
The large-scale microstrip antenna array is analyzed by use of the adaptive integral method (AIM). The resulting integral equations are then solved by the loose generalized minimal residual (LGMRES) method to accelerate iteration. One typical microstrip antenna array is analyzed and the good results demonstrate the validity of the proposed algorithm. Our numerical calculations show that the LGMRES can converge about 6 times faster than the conjugate gradient (CG) method.
