Abstract

A new simple technique to excite microstrip lines with the finite-difference time-domain method (FDTD) is introduced. In the model, the incident voltages are calculated in an auxiliary ID transmission line that is connected to the 3D problem space at the feeding location. The proposed model allows to extract the scattering parameters with a single 3D FDTD run with a reduced simulation time as compared with many of the well-known excitation models. The model is applied to simulate a microstrip patch antenna with an artificial magneto-dielectric material filling.
