Setting Up the Antenna in CADFEKO

To ensure mesh connectivity between the antenna mesh and platform mesh in the steps that follow, create a base for the antenna that will protrude and intersect the platform.

1. Open CADFEKO.
2. Open the antenna model.

3. Create the antenna base and set the region medium to perfect electric conductor (PEC).
   Tip:

   1. Create the base by making a copy of the antenna geometry.
   2. Translate the base to sit below the antenna.

4. Ensure connectivity between the antenna and its base by using one of the following workflows:
   • Union the antenna and its base.
   • Move¹ the base into the antenna union. The Move in operation retains the label of the antenna in the tree.
