CST Tutorial: Microstrip Patch Antenna- Part1

[@JordanEdmundsEECS]

These instructions still work just fine in CST 2017. Excellent Video.

[@tensorbundle]

Thank You. Yes, it is the oldest CST channel on KZbin. I started my CST KZbin channel 7 years ago. Some videos are made in 2010 versions. But my recent videos are based on CST 2016/2017 versions.

[@beny668]

Also how did you get Lf = 31.5 and Wf= 8.7 ??? My parameters are: fr=24GHz, L = 3.43mm and W = 4.253 mm . Would you please kindly help me? thanks

[@snigglefritz777]

Hi tensorbundle, how did you calculate the values for Fi and Gpf? is there an equation? p.s. your videos are great. they're a huge help

[@MrAlphagun]

Thanks for the videos! My questions: (1) Why was Nickel used as a material for creating empty space? (2) How were the dimensions of the transmission line (Wf, Lf, Fi, and Gpf) obtained?

[@pranjalsinghmandloi8662]

idk

[@MrAlphagun]

@@pranjalsinghmandloi8662 Woah, someone replied after 9 years, and the question is still unanswered. I startes watching these videos when I was getting into Microwave research. Since then, I have joined and left this field completely. This feels like my past life.

[@Mr.PandeyRishav]

@@MrAlphagun Ya, I'm also facing the same problem. How did he calculated dimensions of Lf, Wf, Fi, Gpf? Do you know the answers?

[@hamzahm.marhoon9256]

Thank you so much , I think the start point of patch from Mt+Mt to Mt+Mt+copper thickness. Regards.

[@s11x]

Very helpful, thank you !!

[@shirini2007]

how you calculate Wf,Lf, Gpf,Fi? any formula?

[@joashnaidoo8644]

Morons like this think it's so obvious that they don't tell. What a moron!

[@khaledabdelwahab]

Hello there! Do you have any tutorials on Microstrip antennas on EBG ground planes?

[@NassimaTounsinassimasway]

Could you please tell us how did you find thz dimensions Wf, Lf, Fi and Gpf ? They were not mentionned in this video

[@naveenvaishnav9895]

Nassima Tounsi those dimensions are probably mentioned in the research paper he is following. They are not standard dimensions. You choose dimensions according to our need.

[@zhenluo5075]

Nassima Tounsi check some papers you can find it out

[@Mr.PandeyRishav]

@@naveenvaishnav9895 There is equation to calculate Length, width of microstrip antenna but how did he calculated values of Lf, Wf, Fi, Gpf? Is there any formula for these also?

[@redknight344]

thanks a lot!!!

[@tensorbundle]

Welcome. You can watch the new CST 2017 version patch antenna video here: kzbin.info/www/bejne/aKKyo3idarpnfLs And CST MATLAB combined patch antenna design: kzbin.info/www/bejne/rHyrZGiYosmhe6c

[@instituteofcompetitionexpl1588]

Will you please upload the design of rectangular micro strip antenna with EBG structure?

[@tachibanaoren]

thanks for the video...but i dont understand at 5.29...how did you select the face again?..

[@AliOmar-sg2qj]

Great effort. Thank you

[@mdabdullahalfarooqui1416]

once any portion is subtracted using different material (nickel in this case) how to remove this portion (go back to previous state meaning no subtracted part) in case it is needed due to some mistake.

[@andywinfield]

These tutorials are excellent, thanks very much for uploading! Is there any way you could talk me through how you would go about designing a Vilvaldi antenna in CST? I've watched all your tutorials, but can't find anything on the Vilvaldi antenna which seems a bit more complicated!

[@dipankarsaha1568]

how do you calculate Wf,Lf, Gpf,Fi? please help.......please provide necessary formula......

[@tensorbundle]

Basically Lf does not matter. Gpf also doesn't matter much, mostly dependent of PCB DRC rules of minimum spacing. Usually, 0.5mm-08.mm is a reasonable range for Gpf. What matters are Fi and Wf. Fi controls the input impedance and Wf controls the characteristic impedance of microstrip line. You can calculate Wf and Fi from the formula mentioned in Chapter 14 of CA Balanis' book Antenna theory and design.

[@dipankarsaha1568]

@@tensorbundle Thank you sir......If there is an equation for finding out Lf and Gpf? Please email those equation.....

[@Mr.PandeyRishav]

@@dipankarsaha1568 he said CA Balani's Antenna Design book. Did you get those formulas?

[@phoonjzc]

Help I dunno why but I cant substract the empty space I am confused. How do I know which side is the ground plane and which is the substrate. I made it but I forgot

[@narampanawe]

Hi, This lesson series is very useful. I would like to know, how to simulated printed capacitor and inductors with CST. Thank you

[@mehranmemnai]

ow were the dimensions of the transmission line (Wf, Lf, Fi, and Gpf) obtained?

[@saravanakumaran555]

sir i want formula to find height of substrate , length of microstrip feed line , width of microstrip feed line,gap between patch and feed line and Fi. these above mentioned parameter formula i want sir.

[@henzisheeba5474]

Can you please explain how to truncate the sides of the microstrip antenna using CST?

[@449sruthi]

+Henzi Sheeba can u pls tell me what u want exactly?

[@ipman4646]

how if i want to add layer of dielectric slab above the antenna with separation of airgap?...as 1D-EBG antenna

[@phoonjzc]

If I want to design an omnidirectional vs a directivity antenna is there any diff?

hello, please help me to design a microstrip bandpass filter with CST i'm new to CST,your aid will do me a great favour

[@nikoletazacharaki8828]

Hello everyone.I try to design a microstrip antenna with feed line in cst.I use the equations form Balanis Antenna Theroy to find the dimensions for f=2.4GHz h=1.6 εr=4.3(material FR-4) and I get W=38.37mm L=29.76mm but I dont get a resonance frequency at 2.4GHz as I wanted.What else should I check?Thanks in advance

[@tensorbundle]

ΝΙΚΟΛΕΤΑ ΖΑΧΑΡΑΚΗ email me at [e-mail].. I will provide you assistance about your patch antenna

[@nikoletazacharaki8828]

I did.Thank you

[@tensorbundle]

I checked your antenna. It has no inset feed cut for input impedance matching to 50 Ohm microstrip line. Hence most of the incident power was getting reflected and so no resonance at 2.4GHz. I attached the correct version. Check that

[@nikoletazacharaki8828]

thanks,I replied to you in mail.

[@saravanakumaran555]

sir i want design equation parameter for microstrip patch antenna operating at 28 ghz

[@nazmulhasan5915]

great learning

[@tensorbundle]

Thank you 🤗

[@abudzarwan5342]

Sorry sir. can i know how to get Lf. Is there any formula to use? thanks

[@tensorbundle]

of course, there is a specific formula. It's all about impedance matching. Since the input impedance of patch is usually much greater than the 50 ohm microstrip line , we need to move toward the centre of patch because the more we move toward centre, impedance of patch reduces and at a particular location (let's say at Fi) the impedance of patch equals to 50 ohm. That location Fi is our desired dimension. There is an equation to find out Fi. Would you please visit FB group CollabEEE(link in description). I mentioned the formula in one of the threads in that group. Thanks
