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.
-
Define the following variables:
- lambda = 4 (The wavelength in free space.)
- freq = c0/lambda (The operating frequency.)
- h = lambda/2 (Length of the dipole.)
- radius = 4e-3 (Radius of the wire.)
-
Define the following named points:
- cuboidCorner: (0, -lambda/4, -lambda/4)
- lineEnd: (0, 0, h/2)
- lineStart: (0, 0, -h/2)
- offset: (-3*lambda/4, 0, 0)
-
Create a cube.
-
Create a cuboid. By default the cuboid is PEC.
- Definition method: Base corner, width, depth, height
- Base corner: (cuboidCorner, cuboidCorner, cuboidCorner)
- Width (W): lambda/2
- Depth (D): lambda/2
- Height (H): lambda/2
-
Create a cuboid. By default the cuboid is PEC.
-
Create the dipole.
-
Create a line.
- Start point: (lineStart, lineStart, lineStart)
- End point: (lineEnd, lineEnd, lineEnd)
- Translate the line in the negative X direction from (0, 0, 0) to the named point, offset.
- Add a wire port to the middle of the line.
- Add a voltage source to the port. (1 V, 0°, 50 Ω).
-
Create a line.
- Set the frequency to freq.
