Third-Party Integration with Optenni Lab

Optenni Lab is a matching circuit generation and antenna analysis software tool. It includes automatic impedance matching tools and antenna bandwidth estimation.

A macro is provided that creates a link between CADFEKO and Optenni Lab.

On the Home tab, in the Scripting group, click the  Application macro icon. From the drop-down list, click the  Optenni Lab: Port Matching icon.

A Touchstone file containing the S-parameters for the system is generated by Feko and sent to Optenni Lab. A matching network can be created for each of the ports in the Touchstone file. These matching networks are then sent back to CADFEKO to be included in the model.

The Optenni Lab has three run modes:

Figure 1. The Select run mode dialog.

1. Update the model that is currently open and generate all of the required data for Optenni Lab to generate matching networks. A resulting model will be generated where all of the matched ports are reconnected through the matching networks.
2. Use a Touchstone file that has previously been generated by the currently open model and use Optenni Lab to generate matching networks. A resulting model will be generated where all of the matched ports are reconnected through the matching networks.
3. Specify an independent Touchstone file that is not associated with the open model. A matching network will be generated, but will not be connected to any ports in the model.

For multiport models, or models containing multiple configurations, user input may be required. In these cases, a dialog is generated to ask for the required input. At this point, you can provide the active ports, reference impedance, sampling and frequency range settings.
