Abstract
AbstractSince the input impedance of half wavelength dipole antenna is well known, therefore, a dipole antenna is frequently used to validate the computational electromagnetic method. Though its structure is relatively simple, it is not a simple problem for the most computational electromagnetic methods. In this article, we investigate the input impedance of half wavelength dipole antenna using the FDTD method. Numerical experiments have demonstrated that the FDTD method can be used to accurately calculate its input impedance using uniform mesh, nonuniform mesh, or subgridding. © 2008 Wiley Periodicals, Inc.
