Creating the Model

Create the model in CADFEKO. Define any ports and sources required for the model. Specify the operating frequency or frequency range for the model.

  1. Use the model considered in Pin-Fed, Planar Multilayer Substrate Model and rename the file.
  2. Copy (duplicate) the patch part contained in the antenna part.
  3. Delete the antenna part.
    The model should now only contain the patch part.
  4. Create the feedline.
    1. Create a rectangle.
      • Definition method: Base corner, width, depth
      • Base corner: (-lengthX/2, -feedlineWidth/2, 0)
      • Width: -lambda/4
      • Depth: feedlineWidth
      • Label: feedline
  5. Union all the parts.
  6. Add a microstrip port at the edge of the feed line.
  7. Add a voltage source to the port. (1 V, 0°, 50 Ω).
