adding output variables in hfss design

hey guys help me please...
I am designing antenna based on Periodic Reactive impedance substrate for the novel design of patch antenna but know how to add output variables .
Actually i have designed one cell of this antenna....
plz see the attachment....

Hi,

I didn't understand your question clearly. I also looked at your design which looks ambiguous. The boundaries are overlapping. It seems you want to get the dispersion diagram. You should look for the method to simulate the periodic structure.

thanks for the reply..
Actually i am working on a project antenna miniaturization using reactive impedance substrate. I am attaching the pdf related to my project.
My project teacher asked me do it myself that's why i am seeking your help ....actually i have made the antenna for single cell...

Hi,

I will suggest you to first make a simple patch antenna of same dimensions as given in the paper on normal substrate and then make another one on RIS as given in paper. Analyze the antenna on the RIS and compare your results with the one given in the paper.
In order to understand the RIS from the dispersion diagram obtained the simulation of its unit cell, I think there are methods to extract such parameters from S-parameters.
