hello , I'm trying to plan an uwb horn antenna , i already created the the horn antenna in cst but i want to improve its Directivity i would like to add a lens to the antenna but i don't know how to create it via the lens in the horn by cst.. Would appericiate any advices.
Putting a frequency notch in an antenna will also put a big group delay variation in the passband at the notch frequency. Can an electromagnetic simulator program accurately predict the group delay? Maybe. You have to use enough frequency steps around the notch frequency for the equations to converge. You could run a different manufacturer's em
Contact your Application Engineer and request the antenna Design Toolkit. This application is unlicensed, assuming you are on maintenance with Ansoft, and will automatically create many uwb structures including Sinuous, log, regular spirals.
if u have a hfss 11 draw your antenna in hfss and then import it in to cst
Hi, I am wroking on some uwb antenna designs , If you like i can check your hfss file. please upload your HFSS projects. regards
An elliptical monopole printed antenna, for instance
Hi, I'm currently designing a uwb patch antenna using cst MWS. I got all the results i want such as S11,radiation pattern etc. The line impedance of my antenna also got 50 ohms. But what is confusing me is the smith chart not all 50 ohms at my desired frequency (3.1 - 10.6 GHz). Is smith chart still important since i (...)
Hi check this topic may be you will get your problem solved uwb antenna simulation with cst and HFSS
hi all, i am trying to obtain the received signal in an uwb antenna, but i couldn't generate far field source. when i went to solve ==> field source ==> i found that i have to import . is there any way to generate the signal by matlab or even from within cst mws??? thanks
plz help me its urgent....... i m making an antenna for uwb. but my results are not coming right. i m uploading my simulation file. the dimension are right. bcoz this antenna has been made by someone in cst simulater but i m using HFSSv9.0. and yet not get the same or better result... plz help me out this is so important (...)
hello, i m making antenna for uwb but i fail to get the better result. I m attaching file and the dimension of the antenna is right because this antenna has already being made by someone in cst simulater but i m using HFSSv9.0 and i haven't get the same result.... PLZ help

Does anyone work with this type of antenna (monofilar spiral microstrip a.k.a single-arm spiral on microstrip). I post here a paper in which the author designed this antenna with 50 ohm input impedance (real part). But when I simulated it in cst I don't get the same results as in the paper (fig.5 b, c, d). Anyone know how to calculate the (...)

Hi all, I decided to simulate uwb antenna with HFSS, Is it better to use fast or discrete? "fast" takes less time while "discrete" takes longer. To have first impression, fast can be used. for more accuracy, discrete is used. Or it's better to use cst? why? For uwb, cst takes much less time. This is due t

hi, I'm looking for best method for simulation of "uwb antenna" including several patchs on a thick substrate and 2 coaxial feed line,except FDTD. whether FIT method is suitable for this? regards.
dear, please check the feeder of the antenna in the paper that you are mentioned, this may cause the problem. if possible upload the antenna paper that you are referring to.
Hi, I am glad to work with about uwb antennas by FDTD Method. So if you need help you can contact me on my email:
Why you are trying to simulate both antennas at the same time' In my opinion you can save time optimizing both the antennas separately. the accuracy of every antenna can be greater, after you have optimized them you can use some calculation or tool about the link to have an idea of the whole system. Bye
Dear h.f, here are some small guidelines, try not to use FEM codes such as HFSS except for small antennas otherwise the simulation time would be extremely long. The best software for this purpose are IE3D which has a trial version but does not support finite substrate (at least untill version 10) , cst Microwave studio and XFDTD. Try to
Hi Habib83, maybe this FDTD report/code may be of help to you. You may have to adapt FDTD equations to FIT. If you are asking if anyone has simulated uwb antenna by FIT method, cst Microwave studio uses this method and many people has used to to simulate uwb antennas. Cheers, Element7k
