HFSS dualband slot antenna design

Hi, i was trying to simulate the antenna described in the file .pdf, but I have some difficulties to understand how does it function.
I made the design with hfss 13, but i don't know how to apply bounderies and excitations in this case. Have I need to design a coaxial probe to fed the antenna, or i have to apply a port in the position where the chip should be placed?
I would appreciate your help, cause i'm a begginer in this aspects. Thank you all!
