microstrip filter hfss

Hi, I need to simulate a filter using HFSS. What material should I assign to ground plane ? ( I think copper ) I tried to assign copper but Assign material menu is passive so I couldnt assign anything. If I did wrong plz warn me .I attaced the HFSS file plz help me.
 

u can assign copper..i will see the file and let u know
 

there is no need to assign ,make the ground plan to be mentallization.
 

Materials may only be assigned to 3D objects (i.e. a ground plane with thickness). Draw your ground plane and artwork as a sheet and assign a PEC boundry. This will provide quick results. Once you have the desired response copy your model to a new project and assign thickness and material, then look for changes in the response. It will take a long time so solve for meshed metal.
