How to create patch both in the front and back of the substrate in hfss

i am designing MIMO antenna in HFSS.I need to create a bow tie structure in front side of the substrate and backside of the substrate .How to create a bowtie model at the backside of the substrate.i am using "Draw line " command to draw the bow tie structure.Even if i rotate substrate and draw the bowtie structure is shown at the front of the substrate only.

I understood your problem...

After drawing the second bow tie using draw line command it takes the same level of previous bow tie design....

In this situation just select the second bowtie each and every poly lines and change the substrate height in every polyline.


At the end of all changes to all poly lines, you will get the other bow tie design in other side.
