Abstract
This paper proposes a technique for improving the accuracy of the finite difference time domain (FDTD) method for analyzing planar structures printed on a dielectric substrate. The improvement is achieved by incorporating a quasi-static field behavior to the FDTD update equations. The modified FDTD algorithm is applied to printed antennas. The validity of the method is confirmed numerically and experimentally.
