Subdividing a Model Using Non-Radiating Networks
Calculate the input impedance of a circularly polarised patch antenna fed through a microstrip branch coupler. Replace the branch coupler with a non-radiating network and compare with a full solution.
Follow the steps below to solve the model:
- Solve the S-parameters of the feed network separately and export to a Touchstone file.
- Use the Touchstone file in a non-radiating network to feed the two input ports directly connected to the patch.
- Solve the full model of the feed network and patch together.
- Compare the results between the full model and subdivided model.
Tip: Find the completed model in the application macro library1.
