Hello sir I hv follwed the same procedure you have shown in this video but cant create open region and model option is also not showing in my window while designing please help me with this problem….
Devansh Tanna I remember that figuring out how to do this was unnecessarily difficult. I don't have the software anymore so I can't go back and check.. Sorry!
Hello sir, if we want narrower Beam Width and wide BandWidth with good return loss then what exact parameters are to be changed and what should be the minimum value to increase or decrease to obtain the above parameters.
Narrow beam width means you want higher gain. Higher gain means you need to increase the size of your antenna, or find other designs to implement in your antenna that are known for increasing gain. Wide BW will depend on mainly your feeding system, dielectric used, and half wavelengths measurement.
@@chrisheadley808 Thanks for the reply sir. But my operating frequency is 3.5 GHz. Now the wave length is 85.71mm. just halfing the wave length is sufficient or else are there any other parameters which changes once the frequency is changed. Can you please let me know the calculation work, which is very urgent to me.
Moha Farah I showed it in the video. FR4 and copper. I don't understand what you mean by combining the two antennas, like what did I use to connect the? If so I used sma connectors
Dear @@chrisheadley808... i understand all that, but what i mean is, in the end of your Video it seems that you fabricated two antennas in one plane. So, my question is what is the back-plane material you used to put the both antennas on. And how you configured the placement of your antenna to meet the S11 needed. kind regards.
@@xangautam It's standard for the antenna dimensions to be designed at half a wavelength of your center frequency. The half wavelength point in the sine wave is where max power occurs. I did not use a paper to design this antenna although I did reference Hassam's design video as i explained in the tutorial.
Essentially this is a 50 to 377 ohm transformer. When the wave arrives at the board edge, it is impedance-matched and continues in the air.
@@donepearce I think that could be said about all antenna’s
@@chrisheadley808 this is true. But this one has a classic transmission line transformer layout.
So real to shout out professor Leonard

How to obtain a symmetrical beamwidth in both the planes?
thx very much for your video,could u please tell me what ansys edition you use in your video?pls
S mash I think it was 10.1
How do you connect (Multisection λ/4 transformer to the Vivaldi antenna)?
how to determine the values of the variables (TL, s, rate, sL) for the frequencies I need?
Hello sir

thnx for the video,could you u please tell how you got gain vs freq curve??

Hello Thanks for your useful video
Did you do this based on an article?
If you did plz tell me the name of that article.
Thank you

Moha Farah are you talking about the picture at 47:15?
@@chrisheadley808 Yes, please.
Moha Farah that's a piece of cardboard underneath the antennas haha
thank you
sir can you give me the reference where did you find the equations for using this formula
What formula
@@chrisheadley808 sir formula for computing dimensions of Vivaldi antenna😊
@@xangautam there are multiple dimensions. I went over everything in the video.
@@chrisheadley808 I would like to know the references of the equations which you used in your videos for designing Vivaldi antenna sir☺️

Hello Mr. Headly
Could you please say how to calculate rate ?
Look a 3:11. The Rate is R. It's not something you calculate it's just a variable. It's the variable that determines how quickly the curve expands.
What are the operating range of frequencies?
The frequencies at which your antenna radiates at. Whatever frequencies you will be transmitting out of the antenna.
Dear
can you help me about find power received by wireless? link between transmitted antenna to received antenna at what received
It depends on your transmitting power. I'm not a private tutor. Ask your professor or TA.
sir still didnt get the dimensions of feeder and line ..what are the dimensions?
The width I calculated in Linecalc. The length will depend on your design
@@chrisheadley808 sir your MW is 2mm and you have calculated something else...

How to design a planar vivaldi antenna with symmetric radiation pattern.
Hi sir could you please say the process to open hfss in ansys 19
bhargav mamidala click HFSS, and then it opens, Taaa daaaaaa
You can also open an example in the HFSS folder to get to HFSS in case ANSYS software is not working properly.
Respected sir,
cylinder cuts radius is how much.can you tell me and tell me symmetric rectangle dimensions
Sravani Gurrala it depends on what characteristics you want out of the antenna.
we have a same project,but we only have 2 weeks fkkkkkkkkkk
same
Thank you
