Abstract :
Although the finite-difference-time-domain method has been successfully used to model microstrip-fed patch antennas, this has been achieved using uniform grids. The authors show that by using nonuniform grids, in conjunction with first-order absorbing boundaries and broadband excitation, a drastic reduction in computation time can be achieved. Comparison with published data shows no loss in accuracy.<>
