XFdtd 3D EM simulation software has an updated schematic editor to support diplex matched antennas.

Combines matching network analysis with full-wave results, for complex antenna designs involving multi-state and multi-port aperture or impedance tuners and corporate feed networks with digital phase shifters. To simplify the analysis of a matching network’s impact on finite-difference time-domain (FDTD) simulation results, engineers can now connect two voltage sources to a single antenna, improving workflow efficiency for diplex matched antenna use cases. System and radiation efficiencies can be easily computed from a single schematic for both operating modes. Other enhancements include the ability to compute averaged specific absorption rate (SAR) for dynamically tuned antennas leveraging multi-port impedance and aperture tuners. Schematic matching network simulation fidelity has also increased with the inclusion of microstrip models and substrate definitions.
