How to use Planar Multilayer Substrate

RF Engineer

Hi!  I have to add air gap between the ground plane and substrate, and in this case my structure has 2 layers between the Patch and ground plane: (1)Substrate  (2)air. I want to use Planar Multilayer Substrate so that I can use infinite ground plane condition for my simulations, but I am not being able to define 2 layers. Your help will be highly appreciated.

Hello RF Engineer,

 

What seems to be the problem? What have you tried? Have you opened the Planar Multilayer Substrate dialog and clicked on the 'Add' below the table of layers?
