  • Position: set the cartesian coordinates for the position of the antenna. For the antenna, the user can select the position with the mouse by selecting the 'Pick' checkbox and clicking any point in the geometry panel.
  • Dimensions: set the values of the length of the sides (L1 and L2), the separation from the slot (S), the length of the blades (P), the length of the coaxial (T) and the width of the slot (W).

For each modification on parameters panel, this previsualization will be updated for the new parameters.

  • Position: set the cartesian coordinates for the position of the antenna. For the antenna, user can select the position with the mouse by selecting the 'Pick' checkbox and clicking any point in the geometry panel.
  • Dimensions: set the values of the number of slots (Slots), the width and height of the feeding waveguide (a and b), the distance between adjacent slots (d), the length and width of the slots (L and W), the rotation angle of the slots (R in degrees), the distance from the start of the waveguide to the first slot center (P), the distance from the end of the waveguide to the last slot center (S) and the separation from the slot center to the broadwall center of the waveguide (g).

For each modification on parameters panel, this previsualization will be updated for the new parameters.
