Problem with finding and plotting the return loss of microstrip antenna

Hello

I am working on microstrip antenna as my project. I have used Matlab. I have problem to find return loss. I went through sheen paper and took the patch then put it to find reflected and incident waves. but i have difficulty in plotting the return loss. it does not come out similar to sheen's paper. what should I do?

Please help me

You may find the book "CAD of Microstrip Antennas for wireless Applications" Robert Sainati helpful. It includes a batch of design software.

Of course there is the obvious choice of using commercial software Ansoft, IE3D, etc.
