The finite difference time domain (FDTD) method is being widely applied to a microstrip antenna and an electromagnetic emission from printed circuit board. One aspect of this application is efficiently modeling the microstrip structure within the constraints of FDTD approximation. However the calculation results are not satisfied for extremely precise design of the microstrip antenna. The reason of increasing computational error is that the electromagnetic field near the conduction-dielectric interface changes very rapidly. In this paper, a quasi-static approximation is introduced into FDTD calculation in order to improve the calculation accuracy. The validity and exectiveness of this method are confirmed numerically and experimentally.
