Application of the Three-Dimensional Finite-Difference Time-Domain Method to the Analysis of Antenna Parameters

摘要

The Finite-Difference Time-Domain (FDTD) technique has been applied to a wide variety of electromagnetic analysis problems, including shielding and scattering. However, the method has not been extensively applied to antennas. In this paper, calculations of CT2 antenna parameters are made using FDTD and compared with measurements. The agreement is quite good, indicating the possibilities for FDTD application to antenna impedance and radiation pattern.
