Using the pre-loaded scripting library in XFdtd, this video demonstrates simulation of a helical antenna, which is then imported into XGtd for analysis on a satellite. See how XFdtd’s scripting language helps to quickly automate advanced modeling tasks. After the 3D far field pattern is imported into XGtd, the video shows how the software calculates the interaction of the antenna with an electrically large object -- in this case a satellite.
