Can anyone suggest me the ways to use parameters of characteristic modes of an antenna design using feko and implement it in a matlab code for characteristic mode of an antenna?To be more precise suggest me ways to link feko and MATLAB?
i also want to export and run file in feko kindly help. Missing tabs of feko and cst in export mode of magus. It says no models available to export122383
Hi, I'm trying to design a quadrifilar helix antenna in feko 7.0 for use in the 2.4GHz band. The antenna is shown below. The response, specifically the impedance reflection varies quite considerably with different mesh settings. Shown below are the plots for fine and standard meshs. Using a custom mesh with the wire (...)

Hi,Everyone Can anyone help me to design micro strip spiral antenna in feko?? I am not able to set radius of wire and feeding ?? Thank you!
i am doing my project in antenna design using feko software. I had already been through the official feko site regarding this matter. The video tutorial seems to rush through the part where the conformal antenna is made, giving a pretty unclear idea.I projected my patch antenna onto a (...)
There is a how-to page on feko's website on how to create a CPW feed in feko.
I need datas or procedure related to wifi antenna design using feko software
i am trying to design a metal plate antenna with coax feed like this 85760 source : Can anyone tell what s/w these people have used? Currently i am working on feko 6. I used A4 card for coax feed but got an error sayin
Dear Friends I have simulated above antenna using CAD feko & CST at some other institute but still results are far from mention in IEEE paper. Now what should I do. Actually i am designing smart antenna for UWB communication & MIMO system. I am working on both side front end (RF design) as well as (...)
I am doing my MSc project on "design base station antenna using microstrip rectangular array either series or corporate feed operating on 3.5 GHz for Wimax operation on ADS or feko". Can anyone on help me, I will be very thankful to him.
I totally agree with BigBoss. In addition, sometimes the software that works better is the one whose simulated results are closer to the measured data. However, current softwares are really efficient, and most times disagreements are only due to the fabrication tolerances, or on the source definition. However, nowadays designs are simulated with a
Hi, I'm doing a project microstrip antenna using the simulator feko, and I would like to find a model of SMA PCB valid and consistent for simulations that can be used, is there anyone who can help me in finding the actual CAD values ​​of loss tangent and conductivity of the conductor to be used? Thank
I'm designing slot antenna using feko...I need to know design formula for making slot...If anybody know, help me....
i simulated a horn antenna in feko at x band ferequency. i know the feed should be placed at Lg/4 from end of rectangular waveguide and the prob should be L0/4 length. but i dont know what should be the whole length of the rectangular waveguide for achieving minimum VSWR. who can guide me PLZ?
We can simulate antenna results using Matlab but not create a model. You might some antenna design software like HFSS, feko, Empire 3D, or CST
if you cannot solve analitical or numerical electromagnetics and if you have not experience on desgin antenna use antenna magus to designig then simulate the antenna on feko or cst.antenna magus compatible with feko and cst. HFSS may be hardly for you because you cannot (...)
Hey everyone, Please, I would like to design a simple slot antenna with feko. My specification: A thin rectangular slot of half wavelength is to be cut on a finite conductivity, finite size ground plane. The slot antenna is to be fed by a microstrip line on a substrate. Can anyone upload a feko (...)
The best tools in business are CST, Empire 3D, feko and HFSS These are 3D volume meshing tools. They are good for some analysis, but not the best for everything. For planar analysis (PCB, LTCC, RFIC) the planar Method of Moment solvers like Sonnet and Momentum also have advantages.
I think you need to look at antenna Magus for this. antenna Magus can design it for you and export a feko model.
Hi you're never going to get that sort of bandwidth with a patch. Have you considered other antennas? Have a look at antenna Magus. You can export ready to run feko models of lots of different antennas. The Classroom version has 15 antennas and is free to Universities or academics. See www (...)
There are many threads here about EM software. Firstly you should have a look at those. I personally like feko and HFSS. feko is easier to use I think. Although it is not as popular as HFSS it is an accurate and respected German Software. However if you are going to make a simple design try to find a cheaper or free software that makes some (...)
I am trying to simulate an end-fed dipole antenna. its just a two layers antenna, a substrate and an end-fed dipole. Check attached image for the design. The red line is the feeding line. When I simulated it in free space without a substrate, it worked fine, but when I added a substrate layer, I couldn't add a wire port to the feed (...)
I designed 13.56mhz antenna for my fınal project with feko but i couldn't work it,are there somebody who can correct it or deal with feko before,thanks
Hi Friends, Am new to this antenna design, am a student and i have not much clear exposure in this field. It would be very grateful, if anyone can guide me in the following design using feko. Frequency is 4.25Ghz, a)i have to design a pin fed patch antenna with ‘air (...)
what about feko , i heard it id great , but i didn't try it Khouly
It is more dependent of types of antennas and driving circuits you are dealing with, thus in general such problems could be successfully simulated in any of antenna design tools (EMCoS antenna VirtualLab, feko, WIPL-D, CST, HFSS, xFDTD, ...). Also important question is distances you are testing - if you (...)
no need to complex formulas for antenna design investigate the program antennamagus ( ) :D you can download the demo version
Hello everyone, I am looking for a microstrip patch antenna array project, preferably with corporate feed, 4+ elements, on Em.Cube, feko, IE3D or Sonnet. If you have something similar, it would be very appreciated if you can share it. I am working on a science fair project, so any advice on the design of cellular system (...)
i am simulating patch antenna in feko i have all design details i want to know how to design a ground plane
You can use many different software packages like EMC Studio, HFSS, CST, IE3D, MWO, feko, etc. Try as many as you can to better feel differences and possibilities. With EMC Studio it is easy to start, you can obtain evaluation by email request - specify your application in the request. Here is an
I am desiging a tapered slot Vivaldi antenna using a double-sided Marchand balun. I would like to match the input impedance to 50 ohms. I am using feko to simulate the design. I am having issues with obtaining the 50 ohm match and am getting a high reactance value. Can anyone please suggest what I can try to decrease the reactance of my (...)
Hi, you may want to try NEC. Or feko.
I am a usual reader of this forum, due to the fact that I work on antenna design and i have to use simulation software (basically feko and hfss). I think that contact between users is extremly usefull. For these reason want to use Social networks to know new users. For this reason I have created some groups in facebook. Despite the (...)
Hi can anyone give the detail steps to design a conformal antenna using feko..Plz
Hi ongkoy! with helico, simulation by CST will use many time ( because it based on FIT). You can simulated with MoM tool, it solve very easy. example feko, Id3E ( recommendation feko )
What about feko or WIPL-D? MoM will do better than FEM.
how to design single feed circularly polarised antenna in feko for dielectric constant 4.5..which formulas i have to use to calculate the basic dimensions?
i want to design a circular patch with epsr=2.2,h=.1588cm,frequency=10GHz i to design this one plz help..
I hear feko is good for this application. What did you use ?
Hi wiztronix, you may consider feko ( ) for this purpose. I know several feko users have successfully simulated/designed such structures. Attached please find some papers by them. Good luck.
tools for design antenna: HFSS , IE3D , CST , XFDTD , feko some introduction manual you can search here .
Hi everybody! I have to design a microstrip-fed monopole antenna with feko. It consists of a rectangular _patch and a partial ground plane in the back surface of the substrate. My problem is: what means "microstrip-fed" in feko? What kind of excitation I have to use? I hope to have been clear... thanks
before feko, choose hyperboliod by simple geometric analitic concepts. The hyperboloid has 2 foci. One of them is coincident with the paraboloid, the 2nd may be choosed on a convenient Cassegrain region. Then by a simple ray tracing, find diameter of sub reflector. Remeber: choose a convenient position of horn, as horn is far from subref as th
hi, I am required to simulate a microstrip dipole antenna on feko. I have found a reliable design but am having problems with feko. is there anyone out there who is able to help me. it doesnt seem to give me the desired results thanks cheers Alvin
Hi, I am using fekolite software for antenna design purpose. While using the IP card for segmentation parameters and entering the values of edge length and segment length there is a warning shown by it. The warning is Inhomogenous segmentation of triangles. Checking the output file Shows that the ratio of Max./Min. edge length of the (...)
One reason could be that feko is taking in account for some losses that can appear, when the math analisys doesn’t.
