How to calculate the resonant wavelength 51.7241mm ? Is there any formula used? And the Board Width B=(S+lam/4) ,the added extra width lam/4 is for what reason,is it have any effect on S-parameter? Can it be arbitrarily value? Is it just for PCB's board width margin? thanks!
It is simple, f0=5.8 GHz is the considered resonant frequency and the resonant wavelength is calculated using lam0=c/f0=51.72 mm (c is the light velocity in free space). Yes lam/4 parameter is an arbitrary value for simulation space and PCB board (this margin is mandatory but its value is arbitrary).
Very helpful video.. One request that could you design a rectangular waveguide band pass filter (iris)? I am trying to do on my own.. Thank you for this video.
The maximum value of passband is -0.5dB, so in order to determine cutoff frequencies, you should consider 3dB below the maximum value which means -3.5dB.
@@EMSpectrumLab Sir, I tried to do the simulation under CST The response wasn't good unlike HFSS, but for the ports I didn't create sheets, I assigned the PORTS to the higher transverse faces of Z0_1 and Z0_2. Do you think that the problem is because of that? Another question is the adaptation between Z0_1 and Z1_1 is verified even if the width of both Tx_lines is different w=1.009mm and w1=0.854mm. what is the theoretical formula to calculate s1,s2....,sn?
@@aminaaghanim4336 No, I think it can not be related to the size of transvers faces, but you can obtain their optimum sizes via CST built-in macro app. I do not have theoretical formula of "S_n" parameters, you can find them in the literature.
"S" parameter is equal to "2*W+s1+W2+s2+W3+s3+W3+s4". The position parameter of Z0_2 is "-A/2+L+L1+L2+L3+L4 ,S/2-W-s1-W2-s2-2*W3-s3-s4-W ,t+h". Other parameters are clear.
Hi. I want to do a dielectric loaded horn antenna with hfss. But I couldn't make it. I have problem "how can add and a dielectric and simulate with it"? Can you help me about it?
Hi, your video is very well explained and I'm trying to develop a bandpass filter, just like this one, but at frequencies from 26.5 to 29.5 GHz with a cutoff frequency of 28GHz.😁I wanted to know if you could help me or give me some tips
To calculate W, L and S parameters of a coupled microstrip lines, you can use an online calculator like this: wcalc.sourceforge.net/cgi-bin/coupled_microstrip.cgi
Hi, you can see minute of 17 of the video. I showed the optimized parameters. W, L and s parameters are changed. I just redesign the filter for the frequency of 6 GHz.
Hi, watch this video: th-cam.com/video/Jm5QBDsDiHw/w-d-xo.html. I explained the calculation method of design parameters. If you have more questions, feel free and let me know😉
@@EMSpectrumLab Thank you for sharing this video. It was helpful, I have calculated all the even and odd impedences but how can we calculate the W ,L and s parameters for designing? If you have any video related to these calculations then please share with me . Thanks

if I design A band pass filter with range of 2 to 6ghz and my center frequency is 4ghz what should be the values given to create a solution setup

@@EMSpectrumLab Thanks a lot, its really helpful
could you list the values you modified to adjust the centre frequency
You can watch this video in this regard. I explained the design procedure completely. th-cam.com/video/Jm5QBDsDiHw/w-d-xo.html

Glad to help. Yes, I'll upload its video as soon as possible
@@EMSpectrumLab oh.. Thank you very much 😊
@@EMSpectrumLab sir please show with video 4*1 array s21 graph
thank you so much
what are the parameters of Z0_2, please, position . x,y,z ?
Z0_2 is "-A/2+L+L1+L2+L3+L4 ,S/2-W-s1-W2-s2-2*W3-s3-s4-W ,t+h"
Thank you for this great tutorial, Why you choose -3.5 dB and not -3dB please?
The maximum value of passband is -0.5dB, so in order to determine cutoff frequencies, you should consider 3dB below the maximum value which means -3.5dB.

Can you help me in designing folded dipole at a desired frequency with parameter calculation?
What is your problem? I will record a video about this topic soon.
Thank you!
I tried to recreate what you did and I was unable to, primarily because of the values of W, s, and others is NOT clear.
"S" parameter is equal to "2*W+s1+W2+s2+W3+s3+W3+s4". The position parameter of Z0_2 is "-A/2+L+L1+L2+L3+L4 ,S/2-W-s1-W2-s2-2*W3-s3-s4-W ,t+h". Other parameters are clear.

Hi!Can you please help me with the parameters of Z0_2 because they are not in the video and i don't now what to put.
