This section explains how to create a circular spiral.

When the option is selected, the next panel and a previsualization of the antenna with the parameters on the panel are displayed.

  • Position: set the Cartesian coordinates for the position of the antenna. For the antenna, user can select the position with the mouse, selecting the 'Pick' check box and clicking any point in the geometry panel.
  • Other Params: set the value for the radius (R), the width of the strip (w) and the number of turns (Turns). Turns can be a decimal value.

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