yellowtooth said:I am doing some simulations with Ansoft HFSS on IFA.
The 2.4GHz dimension fits good both on simulation and measurment with the reference dimension.
I want to simulate the 5.2GHz IFA, but I have no reference to compare.
Does anyone have the design dimesion of IFA?
Can U give it to me to compare with the simulation ?
Thank U verymuch.

I am also studying the PCB IFA antenna,But I don't know how can I measure it or evaluate its performance accurately. Can you instruct me some points? thanks!
yellowtooth said:In deed, I do need the dual frequency anttenna design method.

The ant I am interested in is I'F'A printed on PCB, but not P'I'F'A over PCB.
Thank U for Ur help.
yellowtooth said:I only simulated the single frequncy IFA with good result on 2.45GHz.
I say good mean that it match the measurement.
But on 5.2 GHz, the result does not accord to the one in paper in microwave and optical.
So I can not solve two frequncy ANT yet.
The reference I have R all from IEEE.
yellowtooth said:S11 !
I want the ant to be both 2.4GHz and 5.2GHz for WLAN and hiper LAN.
So I simulated 2.4GHz and 5.2GHz IFA seperately.
But the 5.2GHz didnot match well while the 2.4GHz matched well, so I think that my model is wrong or the HFSS cannot work at high freqency as 5.2GHz.

I want to use Matlab to simulate the ifa printed on pcb.is it possible?
How can i get the model of the printed ifa.In hfss,can you get the model
from the software. can i get the math formula of the E,H(the variable is the size of the ifa).
