Hello, I have a question about CPS Balun design for array antenna. My concern is that my array antenna have normally a common ground, for example a patch array antenna. Then I would like to convert microstrip transmission line to stripline using CPS Balun. http
The variable of Splitting ratio is the most prominent advantage of FBT splitter(Fused Biconical Splitter) . For example, In the case of the number of users and the transmission distance is inconsistent,we need to be assigned to different optical power line,in this case, the devices require different splitting ratio.And because the (...)

The inverted F "short" can be understood as a matching network using transmission line stubs. I'm not sure if the shown example is actually working, it looks way different than usual inverted F designs.
What are the properties of the interference for noise, reflection and transmission properties? For example from audio to microwave to visible to X-Ray range? Is this to be a passive beacon approach or active response or communicate location determined by robot. What resolution, range and accuracy is required? Beyond line of sight? within? (...)
Hi ing_2012, transmission-line theory is the one of the core topics of microwave engineering. Knowledge of this theory will help you to answer this question, which no one else can answer given the information you specified. See for example this textbook. Firstly, I would ensure that the anten
can anyone help me to simulate EBG structure with transmission line method.. i want to find value of S11.. i dont know boundary setting and background material that i have to use.. i'm using waveguide port but i can't get 50 ohms wave impedance. so can anyone help me? :sad: - - - Updated - - - i mean 50
Hi friends, I have a project review this week.can anybody give hfss model for metamaterial interconnect structures. Read some papers by Caloz.But I know only need any model and IEEE paper on this.example : left handed LC transmission line metamaterial structure. Thanks in advance,
If by "delay" you mean the time it takes for an electric signal to propagate along a transmission line it has nothing to do with either L or C. The propagation delay will depend upon the speed of light in that medium (for example FR4)
My intuitive understanding is that you can't increase the antenna bandwidth with a lossless matching circuit. - - - Updated - - - And to refer to the other problem, one way to generate a resonant structure would be to connect a fairly wide band antenna through a mismatched transmission line of about 7 wavele
hi everybody, may any body please upload the procedure to design microstrip transmission line model using hfss software. the software file along with the pdf is necessary to me. Its a bit imp.
Hi, I am more familiar with digital domain than analog domain. Now I am using Matlab RF toolbox. I find that the example on transmission line is modeled as rational. It is weird that there are only poles in these rational terms, but no zeros in the Laplace formula. Why does it no zeros? RationalFunc = rfmodel.rational with (...)
i have one doubt, if all the lines in electronic circuits are transmission lines or, if the signal wavelength is less than the length of the cable then it becomes transmission line. if it is the case when the signal frequency is less than the length of the line in (...)
I have been struggling with HFSS for the past few weeks trying to get this to work. I would like to simulate a two-wire transmission line. For starters, I just want to have two conductors in air and want to know the input impedance. It would be nice if I could put either a load or another port at the far end of the transmission (...)
I need to know the equation of Dispersion, or if you have the program in matlab for that purpose, could you share it :) (I need it for a transmission line model using HFSS)
Choose for example a X-Band LNA followed by some transmission line, and maybe a down-converter to L-Band. There are sometimes also bandpass filter to reject nearby uplink transmit signals. I can find fine LNA kit out there claiming +/- 1dB gain variation across a passband around 700MHz wide. Some have a second specification, typically (...)
Question for the EM engineers for an aspiring EM engineer: How does the total current flow in a planar transmission line when it has a spurious mode excited? Say for example, you have a CPW with lower ground plane that has various non-desired TE or TM spurious modes exist at certain frequencies. When operating outside these bounds, (...)
87343 hi guys, as above, can i assume that if i want a quarter wavelength line i can simply take 0.25*2*pi/beta(=2633.97)? if say my length ends up to be 500um for example, and the pdk only allows one line to be max of 180um, can i cascade them in series to get the total length required? eg. 180um + 180um + 140um with
Hi, I am reading quarter-wavelength transmission line transformer on an article: The Yin-Yang of Matching: Part 2?Practical Matching Techniques. I do not understand the second sentence about 22%. This percentage is regarding to which bandwidth? It gives as an example of the first sentence, i.e. for ratio 6:1, it is narrower? I do not (...)
