Matching Network Design And Simulation In XFdtd
The process of antenna design simulation has become more complex for RF engineers. Sophisticated wireless devices must be capable of operating in multiple frequency bands. At the same time, device dimensions are shrinking, resulting in crowded internal layouts that must accommodate many components and multiple antennas.
Advanced Matching Network Analysis in XFdtd
Remcom’s XFdtd EM Simulation Software offers unique capabilities to help engineers navigate antenna design challenges with speed and accuracy. In particular, XF includes several innovations that simplify matching network design, including a schematic editor and the Circuit Element Optimizer.
XF includes a unique schematic editor specially designed for analyzing matching networks and corporate feed networks. The schematic editor visually characterizes the impact of a matching network design on even the most complex antenna systems.
- Combines matching network analysis with full-wave results.
- Improves workflow efficiency for diplex matched antenna use cases.
- Supports simple pi or T matching networks, multi-state and multi-port aperture or impedance tuners, and corporate feed networks with digital phase shifters.
- Delivers a comprehensive collection of critical full-wave results: near field heatmaps, far zone patterns, system efficiency, and more.
The schematic editor also includes tuning slider bars that enable the manipulation of inductor and capacitor values in real time. Users can adjust component values using the sliders and immediately analyze how the changes affect the circuit’s behavior. Final states can be committed to the schematic permanently or added to a new operating state.

Circuit Element Optimizer (CEO)
XF's Circuit Element Optimizer is a feature that selects the optimal component values for matching network layouts. CEO uses full-wave matching circuit optimization (FW-MCO) to analyze the impact of parasitic effects on full-wave results, including radiation efficiency, system efficiency, and S-parameters.
CEO addresses the challenge of inter-band carrier aggregation and multiple frequency bands by optimizing the lumped circuit elements directly in the physical matching circuit layout where the EM coupling from multiple antennas and the ground return current paths are taken into account.
