Matching the Antennas with Optenni Lab

Use Optenni Lab to match the antennas. Use the application macro Optenni Lab: Port matching”.

These examples are also available as tutorials1 in the Optenni Lab installation. The different matching options are also provided in Optenni Lab.
  1. From the Application macro menu, select Optenni Lab: Port matching. This launches the Select run mode dialog.

    Figure 1. Options for running the Feko-Optenni Lab link.
    Note: If the first run mode is selected, a new .cfx file is created and the unmatched S-parameter simulation is executed.
  2. Select Use existing data for the current model and click Next.
    This sends the Touchstone results to Optenni Lab to design the matching circuit.
  3. Generate the matching circuit by following the steps in the Optenni Lab tutorials and documentation.

    Figure 3. Dual antenna matching network (Optenni Lab) and general network (CADFEKO).
  4. Right-click in the circuit view and select Transfer circuit to Feko and quit.
    A new .cfx file is created automatically when the matching circuit is added as a general network.
  5. Run Feko to obtain the matched antenna S-parameter.
