Methods for shorting the patch and the ground plane

i want to short the patch and the ground plane if i do so by uniting all the ground plane shoring cylinder and patch it gives error patch and substrate intersect.......bt if i only make the cylinder just touching the patch and ground plane it dsnt give error


is this right method of shorting or is it necessary to unite them.....plzzzz suggest some possible solution to it in regard to hfss

There are several options to get connectivity between shorting pin and ground plane:
In case they intersect:
1) Substract short pin from ground plane (save the original shape option has to be selected)
2) unite them

In case they don't intersect just leave them as they are, but you have to verify that
are touching each other (same z-coordinate..)

It doesnt mind for HFSS which option you will choose
Good luck

what do you mean by "(save the original shape option has to be selected)"?
I've the same problem and I don't know how to solve it..... I'm getting desperate. Thanks
