kayaoo said:yellowtooth,
I am working with a+g antennas too.
I simulated the dual band F(Wang) and IF(Greece) antennas in hf$$ and got results very close to the two papers.Maybe two sepperated sweep bands or more meshes for high band are better.
In hf$$v9 it is very easy to change the length using parameters,while in V8, macro languages is needed to using parameters.u can find it in file->macro->history menu. Of coure ,ur method works too. Hf$$ runs well in a high frequency.

Element7k said:Hi all,
here is the return loss simulation plots of the Printed IFA (Wong) in C/S/T & H/F/S/S.
I am not sure if H/F/S/S simulations are accurate over broadband but the comparison seems quite ok to me.
Antenna parameters in SAT format. If anyone can optimise the antenna, pls share new parameters.
Many thanks.
Cheers,
Element7k
eirp said:Dear Element7k,
please can you post your hf$$ project also?
You know I'm still curious about pml settings there.
Thanks in advance, buddy!!
Best,

kayaoo said:hi all,
I simulated the three antenna. the simulation of Wong's dualband F-shape monopole antenna shows a good accord. Karakoussis's dualband invert-f antenna has a slight offset in resonating frequencies. but when the thickness is tuned from .2mm to .7mm the result is then ok. (I think .2mm is too thin to support such a pcb antenna).
however the simulation of wong's dualband invert-f antenna gets a quite different result which shows the antenna has a resonate frequency in about 2.7G and NO obvious resonate in 5G band and the low band is relatively narrow.Two things are not mentioned in the paper which are the short via structure and the feed structure.further more,I had toke it for granted that all the metalstrips in the F structure owned a same width (3.05mm) until i found Element7k's ".Sat" file. But how did u know all the dimensions which is not mentioned in the papers? The s11 plot in the paper shows the antenna has some benificial parasitic effects which may come from the feeding coaxial cabble or anything else and lead to a very wide band in 2.4G. I don't know why.
to yellowtooth: In v8,u can first copy the project in the project manager when u can select the "copy project only" selection. this selection will make a small project without result.
btw, I'm not good at C$t MW$ but in my first tries the sw seemed much slower than HF$$ in simulating the antennas mentioned above. My MW$ is v3.2 and HF$$ v9. Is that true?

wolf303 said:Dear Element7k:
how can i open your *.sat file in hfss8.0? can?
can you upload your project(hfss 8.0) about printed ifa simulation?without being solved i think the size is small. i need your help!
i do not know how to draw the model and set the boundary?do you have some example about printed antenna simulation?
