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:
- d = 2.25 (Distance between dipole and plate. [3*lambda/4])
- h = 1.5 (Length of the dipole. [lambda/2])
- a = 4.5 (Half the plate length.)
- rho = 0.03 (Radius of the wire.)
-
Create the dipole.
-
Create a line.
- Start point: (d, 0, -h/2)
- End point: (d, 0, h/2)
-
Create a line.
-
Create the plate.
-
Create a rectangle.
- Definition method: Base centre, width, depth
- Base centre (C): (0, 0, 0)
- Width (W): 2*a
- Depth (D): 2*a
- Rotate the workplane of the rectangle 90° around the V axis.
-
Create a rectangle.
- Add a wire port (segment) to the middle of the line.
- Add a voltage source to the port. (1 V, 0°, 50 Ω).
- Set the total source power (no mismatch) to 1 W.
- Set the Frequency to c0/3.
-
Specify the symmetry about 2 principal planes:
- Z=0: Electric symmetry.
- Y=0: Magnetic symmetry.
Tip: Exploit model symmetries (if it exists) in a large or complex model to reduce computational costs.
