CST Tutorial : Complete Vivaldi Antenna Simulation in CST part2

[@ahmedhelmirefaie6784]

thanks for the great effort , keep up the good work , engineers around the world need such great tutorials :)

[@the_ALchannel]

Very cool and useful, cheers to you from russian pulsed power designers :)

[@exolein]

Dear Tensorbundle many thanks for your work and time. I think many people relly appreciate it!!! There is one important definition missing. The background material should be defined as normal. The default is PEC which leads to an error in the precalculation of the simulation.

[@tensorbundle]

Dear viewer thank you for watching. The background material definition in CST under MW, RF, & Optical>Antenna Planar template is already by default normal

[@Malek1p2]

Thank you. Great explanation

[@tensorbundle]

You are welcome!

[@pratulnijhawan4386]

Sir,how is the frequency range 38-43Ghz related to parameters you took for antenna design. For ex if I have to design for 900Mhz to 3Ghz,what modifications in the design are required?

[@bikashsahoo9152]

Thank you so much sir, please help me to design vivaldi antenna for sub 6 GHz, what are the formulas to apply for finding the parameters , please send me the link.

[@amitagarwal8614]

i followed the each step from your video exactly but getting the different result than yours. did u do any changes after 4:50 ?? if yes then what ?

[@tensorbundle]

No. You should double check your setup.

[@amitagarwal8614]

yeah actually by mistake i put the value of QWM 0.5 instead 0.9. Getting the correct output now. thnks for replying btw :)

[@amitagarwal8614]

sir i need one more help . actually i have to submit my final year project this weekend in which i have to design three bands 1-2, 2-4 and 4-8 Ghz. any idea how to get these bandwidths ?

[@mehulthakkar601]

Hi if you want to keep varactor diode in this design then how can we do it?

[@MrKaizen75]

Great video! Helped me a lot!

[@tensorbundle]

Thank you. Please like it and sbuscribe

[@andrescastel7]

thanks man, i love you, hahaha, you make my semester more easy, and i can understand so much!!!!!!

[@tensorbundle]

:D thank you so much

[@sersheva]

Excellent work thanks for the tutorial! I have a question how can I go from CST to ADS? to simulate with circuits like LNA. Thank you.

[@tensorbundle]

Extract S1P file from CST simulation and use S-param block in ADS and link that S1P file with that block..I have a post on similar topic in CollabEEE, although it was meant for HFSS but the principle is same for CST too

[@amitagarwal8614]

has anyone the design of vivaldi or any other antennas for the bands 1-2, 2-4 and 4-8 .plz share!!

[@canaristlemcen3947]

How do I control the parameter sweep in CST using Matlab?

[@isahmusadanjuma5271]

Thanks a lot for this tutorial. Pls which parameter will I change to get my -10dB return loss when the frequency is from 1-4GHz not 30 t0 60GHz as in this design. Once again Bravo Zulu to you.

[@tensorbundle]

Study the paper by PJ Gibson, "The vivaldi aerial''. All info is there

[@akshitagupta1383]

tensorbundle no i don't get any info there

[@yasinhosgor4403]

First thanks for all videos, great work. If we use radial stub instead of straight microstrip line , How could we calculate port extension coefficient or how could we simulate Vivaldi antenna using radial stub ? Would it be the same like in this video ? If radial stub is at the top layer or at the bottom layer of antenna , does it change the calculation port extension coefficent ?

[@tensorbundle]

it will remain same

[@isahmusadanjuma5271]

thanks a lot

[@mohdfarmanaliAli]

How to do meshing???

[@tensorbundle]

please watch it for mesh generation menue of cst kzbin.info/www/bejne/hqPKloepqbl3f6s

[@tensorbundle]

and For improved visual properties and clarity of the same vivaldi antenna, watch this version: kzbin.info/www/bejne/jmHGamRsYqZ6p68

[@ShashiKumar-sn5fg]

thank you very much sir. it helps me a lot to learn about vivaldi antenna. sir actually i have to design vivaldi antenna for 2GHZ operating frequency. can you please help me to design? please sir.. ?? actually i am not able to take Dimensions.

[@tensorbundle]

Shashi Kumar Just start with a basic frequency scaling operation and start with a roughly estimated dimensions. Simulate and see the results and change the dimensions to meet your design frequency. Search some vivaldi antenna research paper from IEEE xplore and start studying and grasping the underlying theory. The rest would be piece of cake after that.
