We are designing and fabricating a micostrip fed vivaldi antenna in the frequency range of 1GHz-3GHz. We are most likely to use FR4-Epoxy as the substrate. However, we are not certain about implementing the equation for the exponential taper of the vivaldi antenna in hfss. Request your help in this regard.

Try getting hold of some masters thesis on vivaldi antenna, U should be able to get one in scribd. A thesis would give u a good start with work and good references too..!!
in edaboard search vivaldi i seen a text about curve of vivaldi i hope it helpful for you
Hi everyone, I'm trying to simulate Antipodal vivaldi antenna in hfssv12, but when I do it, something's wrong in all diagrams, so I think that antenna isn't working properly. Is there anyone who could see this antenna and tell me what's wrong with it's design, so I could simulate it properly and get some (...)
Can anybody suggest me how can I change the wave impedance of an antenna in hfss. My interest is to simulate UWB antennas like vivaldi, LPA, and Bowtie.
may be possible but the size of antenna is too much but with taper you able reduce size like vivaldi
Hi, Any one who has used equation based curve/surface option to generate 2D structures in hfss would like to upload any document or example explaining that how to do it ? I am trying to use this option to draw exponential curve of vivaldi antenna but em not successful yet. Any help from anyone who is expert on this would
Hi, I use CST to simulate of tapered slot antenna (vivaldi) and when I measure the antenna (that I create by using CST), it find that the results from CST and measurement are the same. So, I no have idea about ADS. :smile:
i am reading some papers about this antennas, but i have another question: how can I get the equations for to determinate the curvature of the flares and how can i drawing or with which tool can i do this in the software hfss???...... i think that will be a good idea design an antipodal vivaldi antenna in the range of (...)
For the vivaldi antenna, at what frequency are you planning to design? On which substrate are you planning to fabricate. I simulated different vivaldi antennas in hfss. You can see the attached figures (exponential tapers). But in order to fabricate the vivaldi antenna and (...)
how to do optimazation on hfss
Hy everybody. I'm a student and i want some urgent help if someone with enough time can help me. I have to design a vivaldi antenna with f=0,4-2 GHz Directivity characteristic at 3dB= 100-120 deg G=3dB Zin = 50 ohms VSWR < 2 I have all the documentation and everything else but i have some small problems wi
I want to simulate an 8 x 8 vivaldi array with triangular grid configuration in hfss. Can anybody help me in setting up the problem so that i can assess the performance of element in array environment
Hello,everyone! I am working on vivaldi antenna CST simulation.The S11 is very big and i think it is wrong.I did the simulation for the same model in hfss before,and the result are quite i guess the problem is CST setting,however i can't find where the problem is exactly. Can anybody help me to solve it? I appreciate... P.S. i post the
I have some serious doubts can anybody clarify these pls. 1. effect of metallic ground plane on vivaldi antenna (i made some traveling slot antenna with 120 deg HPBW in both planes but in practical its not behaving as in simulations by hfss)..kindly put some light on feed SMA connectors and mounting structure 2. seen (...)
i am doing the vivaldi antenna for 8-12 GHz. and i use RF-35 substrate material which dielectric constant is 3.5. After i designed all the parameters, i don't konw how to simulate it. Does anyone can help me to solve this problem please?? AS it is very urgent!!!!! PLEASE HELP!!!!
Hi, how to use hfss to design and simulate a vivaldi antenna?
Hi group! I have to simulate a vivaldi antenna with CST and with hfss, and then I have to comparate the results. My antenna is a vivaldi Antipodal Balanced (you can see that, if you go to CST home page=>applications=>antenna and sar=>... vivaldi). I have dimensioned my (...)
Hi, Are you any practical experince about vivaldi antennas? if Ok, please go to this forum: I have s problem with this antenna, Please Help me. Thanks KMPA
