(Urgent): Please help Microstrip antenna excited by microstrip feeding in HFSS

Hello
I am working on a project of simulating a microstrip antenna to verify the results obtained in a published paper (attached)
I am kind of new to HFSS and I can't excite the antenna to get the published results (specially the radiation pattern)
I am working on HFSS v11 and have attached the design file I created (there may be errors (not in geometry, but may be in air!)

can anybody help me please?

THANK YOU ALL

Can anyone help me please...

its not necessary that you get exact results, they may be slightly different because of different softwares and different settings
