PIFA in HFSS - how to feed the antenna in HFSS?

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.

please >>>
if any body have the design ....put it here.
thanks

hi
PLs say the paper title and author to i saw it and i never seen PIFA in ADS but i attach a help about design of antenna in ADS

thanks for replying but my project about "design of dual band PIFA antenna using HFSS"

 

[ferdows]

hi which bands u want to design antenna and what kind of pifa?

 

[angellife]

my reference paper is
"Thin Internal Planar GSM/DCS Mobile Phone Antenna" (type on google ISCON05_00047)

hi
i seen the paper whats u problem with this paper?????

 

[angellife]

im still new on HFSS, do you advice me to work on this paper "is every thing clear" and can i simulate this antenna

 

[ferdows]

hi
u can simulated this antenna and u can email me and u can find it in my edaboard page

 

[angellife]

i cant find it in your page, any case i am start to design it ....if you have its design put it here please.thanks

 

[ferdows]

hi
i design and simulated it for u and attach it but i advise u to try design by your self i hope it will be useful for u
my email:ferdows_j@yahoo.com

thank you....i have nearly 35 days before my discussion (i'll study it and try to add improvements on it)...

[robertj]

hi....i have to design the same antenna ,,but i have a problem with coaxial feeding >>please help

 

[ferdows]

whats your problem ? send your file

this is my design i need coax feeding like the paper

 

[angellife]

this is my design, i try another type of feeding and it gives me the same results

thank you for your reply but i need the probe feeding method>>>
