Defining an Infinite Plane

Define the infinite ground plane and substrate.

  1. On the Construct tab, in the Structures group, click the  Planes/arrays icon. From the drop-down list, select  Plane / ground.
  2. On the Plane / ground dialog, in the Ground medium groupbox, click Planar multilayer substrate.
  3. For Layer1:
    1. Set the layer Thickness to substrate_h.
    2. Set the layer Medium to substrate .
    Note: For this example a PEC ground plane is required at the bottom of layer 1. This is the default setting.
  4. Click OK to create the infinite plane and to close the dialog.

    Note: The model was created so that the Z coordinate of the top face of the substrate (Layer 1) is 0. For models where this is not true, remember to change this default value at Z value at the top of layer 1.
