DesignForge: One-Shot 10 GHz Wilkinson Splitter in HFSS

Overview:

At DesignForge AI, I build RF knowledge into the platform so the agent has the context it needs to execute one-shot designs directly in Ansys HFSS. A simple example is a Wilkinson power splitter at 10 GHz:

  • Trace widths are set for 50 Ω from the dielectric and frequency, using deterministic scripts.
  • The agent accounts for the extra capacitance from parasitics at higher frequencies, and sweeps a correction factor to find the best length for the quarter-wave traces.

Result: S11 = −16.79 dB, S21 = −3.21 dB and S23 = −25.56 dB.

Built on PyAEDT, the Python scripting library for Ansys HFSS.

The agent sets up the splitter in HFSS, sweeps the quarter-wave length, and reports S-parameters.
