Hi Dear.
you can followed these steps in HFSS to create a SIW structures.
1- draw a box for substrate
2- draw patch & ground plane(top and bottom of sub respectively)
3- draw cylinders around the patch for creating the SIW.
4- select top faces of all cylinders that you draw in previous step,then go to modeler-surface-create object from face
5-select bottom faces of all cylinders and done the same manner in step4.
6-select side faces of all cylinders and done the same manner in step4.
7-subtract patch and faces that create in step4.
8- subtract ground and faces that create in step5.
9-assign Perfect E for all faces that create in step6.
10- finally subtract all cylinder that create in step3 from substrate.
