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. Define the following variables:
   • fmin = 100e6 (The minimum frequency.)
   • fmax = 300e6 (The maximum frequency.)
   • wireRadius = 1e-3 (Radius of the wire.)
2. Define the following named points.
   • point1: (-0.01, 0, 0.5)
   • point2: (0, 0, 0.01)
   • point3: (0.01, 0, 0.466)
   • point4: (0, 0, -0.01)
3. Create a line with the start and end coordinates of point1 and point2.
4. Create a line with the start and end coordinates of point2 and point3.
5. Copy and mirror the two lines around the UV plane.
6. Create a line with the start and end coordinates of point2 and point4. Rename the label to feed.
7. Union all the lines.
8. Add a wire port to the middle of the line.
9. Add a voltage source to the port. (1 V, 0°, 50 Ω).
10. Set a continuous frequency range from fmin to fmax.
