Introduction to the Compare Window in Antenna Magus

The Compare Window allows comparison between multiple Antenna Magus designs, according to physical size, performance and associated extracted values.

Designs are compared by adding them to a Compare Set. This is done by using the Add to action on the Ribbon in Design Mode. Using the Add to action can send a design to a new Compare Set or to an existing one. While a design can be added to a Compare Set before or after it has been estimated, the Compare Window itself can only be opened after at least one Compare Set has been created.

The basic layout of the Compare Window is similar to the Antenna Magus main application window, comprising of a number of areas, as shown in the image below.

Figure 2: Basic layout of the Compare Window

The Compare Window shows a collection of Compare Sets. The designs that form part of the selected Compare Set are shown in the Palette, grouped by Template type. The content displayed in the Workspace, depends on the selected perspective. The available perspectives are Model Preview, Estimated Performance or Value Compare. Various actions relating to these views are available in the ribbon.

Model Preview Perspective

The Compare Window opens in the Model Preview perspective. All model preview options available in Design Mode are available in the Compare Window. To allow relative size comparison, all 3D previews of the various designs in the Compare Set are shown with equal scaling.

Estimated Performance Perspective

In the Estimated Performance perspective, performance values / traces of the different designs in the Compare Set may be compared. The Compare Window allows the user to select which charts are shown (Chart Groups), and select the content on each chart (Chart Sources). The Chart Groups and Chart Sources may be edited from the ribbon.

Value Compare Perspective

The Value Compare perspective provides a tabular overview, listing the Objectives, Parameters and Derived Quantities of all designs of a Compare Set.

In addition, reference values may be selected. When a reference value is selected, other values in the same table and with the same unit type will show a percentage value indicating the difference relative to the reference value.

To aid further value comparison, three types of reference selections are possible:

1.    Single Reference Select

2.    Row Reference Select

3.    Column Reference Select
