Active fresnel reflectarray in cst mws. What conditions must be set to obtain the cor

Good day. I began to study Active fresnel reflectarray in cst mws and decided to try to repeat the results from paper " New Antenna for Millimetre Wave Radar". However, I can't get the same result. What conditions must be set to obtain the correct result? Any additional information I will send you by mail. Thank you very much in advance.
The application contains:

• My and others' S11 parameters
• Sizes
• Picture for explanation of sizes
• And the model.
