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:
    • 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.)
  2. 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)
  3. Create a cube.
    1. 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
  4. Create the dipole.
    1. Create a line.
      • Start point: (lineStart, lineStart, lineStart)
      • End point: (lineEnd, lineEnd, lineEnd)
    2. Translate the line in the negative X direction from (0, 0, 0) to the named point, offset.
    3. Add a wire port to the middle of the line.
    4. Add a voltage source to the port. (1 V, 0°, 50 Ω).
  5. Set the frequency to freq.
