Constructing the Yagi-Uda Antenna

Build a parametric model of a Yagi-Uda antenna. Use variables and named points already created.

  1. Create a line (active element).
    • Start point: (0, 0, -yagi_li/2)
    • End point: (0, 0, yagi_li/2)
    • Label: yagi_active
  2. Create a line (director element).
    • Start point: (0, -yagi_d, -yagi_ld/2)
    • End point: (0, -yagi_d, yagi_ld/2)
    • Label: yagi_director
  3. Create a line (reflector element)
    • Start point: (0, yagi_d, -yagi_lr/2)
    • End point: (0, yagi_d, yagi_lr/2)
    • Label: yagi_reflector
  4. Create another director element.
    • Create a copy of the yagi_director element.
    • Translate the copy from (0, 0, 0) to (0, -yagi_d, 0).
  5. Create another director element.
    • Create a copy of the first yagi_director element.
    • Translate this new copy from (0, 0, 0) to (0, -2 * yagi_d, 0).
  6. Union the lines and rename the resulting part to yagi_antenna.
  7. Place the Yagi antenna in the correct position and orientation.
    1. Rotate the yagi_antenna part around the N axis by -(90+15)°.
    2. Translate the yagi_antenna part from (0, 0, 0) to (yagi_centre, yagi_centre, yagi_centre).
