Abstract
A method of improving FDTD calculation accuracy for printed antennas is proposed. The quasi-static approximation of an electromagnetic field is incorporated into the FDTD update equation by using the integral form of Faraday´s law. A few examples of printed antennas are analyzed using the proposed method. Significant improvement has been achieved in calculation accuracy, even if the same cell size as the original FDTD is used.
