Overlaying 2D Radiation Field Plots on Models

You can overlay Radiation Pattern plots (with restrictions) on the geometry in the Modeler window. The eligibility depends on whether the plot is defined on a single plane. For a Radiation Field plot, you right-click Results in the Project tree, and click Results>Create Far Fields Report>Radiation Pattern.

There are two cases of eligible radiation pattern plots for overlay, defining a single plane in a 3D Polar Plot.

• Primary sweep on "Theta" and with one value for "Phi" in "Families" of curves, typically 0 or 90.
  
• Primary sweep on "Phi" and with one value for "Theta" in "Families" of curves and "Theta" is either 90deg or -90deg.
  
  

Note that the plot can contain multiple traces within this plane - for example traces for multiple frequencies of a discrete sweep. The Radiation Pattern plot will overlay on the 3D view, in the appropriate rotated plane of the far field CS, and include all traces and the axes/grid. There is no need to show the title or legend.

Radiation Pattern plots are added to the Overlay radiation field dialog that displays when you right-click Field Overlays in the Project Tree and select Plot Fields>Radiation Field... from the shortcut menu. The dialog lets you toggle visibility for the Model window and set plot parameters for Transparency, Scale, and Type (2D or 3D).

There are several cases mentioned above where an overlay will not be valid for display. This includes any radiation plot that has multiple planes. The Overlay radiation field dialog always lists all possibly overlays for selection, whether they are valid or not. However, if you check the Visibility column an overlay that is not valid, and then click Apply, the text field in the dialog gives a warning describing why the overlay is not valid, and then unchecks that overlay. Similarly, if a valid overlay is already being shown, and then you edit the plot settings or antenna parameters such that the overlay becomes invalid, the visibility column becomes unchecked and the overlay stops displaying.

You can then use Modify Report to change the plot based on the warning to make it valid for display. Typically, you can select the Families Tab, and select the desired Phi value.

When the plot is valid, Apply then shows the plot in the modeler window..

If you have Saved Antenna Parameters for Overlay, you also use this dialog to control whether to display a table of antenna parameters. See Antenna Parameter: Save for Overlay.
