Abstract
This paper proposes a technique for improving the accuracy of the finite difference time domain (FDTD) method to analyze a short dipole antenna. The improvement is achieved by incorporating a quasi-static field behavior into the FDTD update equations. A closed form of the quasi-static field is obtained from a low frequency limit of a sinusoidal current distribution. The effectiveness of the modified algorithm is tested by comparing with the method of moments (MoM).
