PIFA in HFSS

I have a problem in designing PIFA, I don't know how to feed the antenna in HFSS.In IEEE paper said " A 50 ohmi coaxial line is used to feed the antenna.
Specifically,two folded feed lines are placed between the radiator patch and the feed point". I specified that the feed point it's at the second line(Patch_9 in design) .The FR_4 is considered to be the groud plane,and if someone could tell me the next steps I have to follow in designing the antenna. I have some tutorials but that can't help me very much.
And another questions are about a multiband internal antenna with a RF feed,that must be designed in ADS-how can I do this? and second:can I import a PIFA design from HFSS to ADS?Thank you for your help.
