Based on the Maxwell's equation, the finite-difference time-domain method presented in this paper is efficient and accuracy for modeling and analyzing the micro-electro-mechanical systems multiplayer microstrip patch antenna studied by our lab. The antenna characteristic parameters are discussed by the result of simulation. It implements relatively compatible absorbing boundary conditions.Saving the computer memory and CPU time.
