Antennas 6.3

9. Radome

The Radome menu contains two options: "Define Radome" and "FSS Primitives".

Radome submenu

Radome menu

The "Define Radome" option allows the user to generate a radome, including interfaces and materials. Every radome layer is bounded by two surrounding interfaces and the material defined on the inner interface. Click on   to add a new radome.

Radome Definition Tab

"Interface 1" is the most inner one, select its geometry and select the interface on the table, then click on Set Objects.

Set objects on interface 1

Repeat the process with all interfaces. Then select the layer material clicking on the material cell.

FSS geometry can be added to the interface. First, create the FSS geometry using ArrayOnSurface command. Select its geometry and select the interface on the table, then click on Set FSS Elements.

Set FSS Elements on interface 2

Hybrid MoM-PO Method: Simulates the antenna and the radome separately. MoM is used to analyzing the antenna and the radome is simulated by using PO. Select "Physical Optics (PO)" in Solver->Parameters menu.

The "Antenna Results" checkbox enables meshing and calculating the antenna system without the radome structure. This option enables "Insertion Losses" and "Boresight Error" and allows to compare the results when the radome is considered or not.

Click on "Save" button to save the radome parameters.


On the other hand, the "FSS Primitives" option under the "Radome" menu allows the creation of a wide variety of periodical structures primitives. For more details about each one of these primitives, see the Primitives section in the GUI User Guide.
