## what is the mode for bend transmission line?

Hello, guys You know, we learn from the textbook that the field mode analysis of transmission line is idea i.e. the transmission direction is along z axis and the mode is TEM. Then, how to analyze the bend transmission line mode? What makes the wave bend also? you may say that the current (...)

## matlab code for rectangular microstrip patch antenna and hfss software request.

Hello friends, am designing a rectangular microstrip patch antenna. I used transmission line method to calculate the parameters but need software for other analysis.Please, let someone help me with the matlab code and hfss Software. Thank you for your quick response. Mathson

## EHV T.L Software (Simulator)

Hi, I am having a course about Power systems transmission. Here is a brief description about this course: This course is divided into two parts: electrical and mechanical design and analysis. The electrical part includes topics such as basic concepts, extended review of overhead transmission line parameters and steady (...)

## transmission line simulation

I did some simulations of the ideal transmission line in LT spice using LC chain with 2.5nH and 1pF which results in 50Ω transmission line. The transient analysis gives result that i expected - no reflections if chain is properly matched with 50Ω. But in AC analysis the amplitude (...)

## Differential Transmission Line in Cadence (Behavioral Modelling)

Hello everyone! I am trying to model a differential transmission model for my lvds application. I first found out that for visual applications ribbon cable is the one commonly used for small distances upto 0.5m. I looked up the spec, dimensions and dielectric properties of the ribbon cable and modeled it using the strip line model of (...)

## Reflection Coefficient of Cascaded Transmission Line

I have a series of 5 transmission lines connected in series. I was wondering how best to analyse the circuit. I am not entirely sure how to calculate the reflection coefficient of the TL. Consider the following: o-----o-----o-----o Z1\,\,\,\,\,\,\,\,\,\,Z1\,\,\,\,\,\,\,\,\,\,Z2\,\,\,\,\,\,\,\,\,\, | 50 Ohms o-----o-----o-----

## defining ground plane in ads 2011 momentum setup

hi all, I ve been searching thru the similar threads, and I see that there is not a clear consensus on the way we can define the ports in momentum simulation setup for ads version 2011; (NOT the 2009 version). My question -however it may sound silly- is as follows with the figure below: In this figure the orange colored line is a thick top

## modal analysis of MEMS shunt switch in coventorware

hi.... Am working in RF MEMS... while doing the modal analysis of MEMS shunt switch of CPW configuration in coventorware, am getting the modal displacement in the transmission line instead of beam... pls let me know why this happens and help me in rectifying this. regards. Thilaga

## Free*PSpice*alternative

Ubuntu has a host of free simulation tools- NGSpice, KICAd, and apart from these there are lot of tools on Smith Chart, transmission line calculation, Timing analysis etc.,

A long time ago I had to do an analysis to determine whether it was feasable to use tuning stubs to balance a transmission line. As I recall, the reactive component was dependant on the length of the line with respect to the wavelength. How does cable capacitance figure in, and why is it ok just to terminate the receiver (...)

## [ASK] Band Pass Filter Transmission Line Effect 145 MHz

Hello. I want to design Bandpass Filter with Specification : f = 145.95 MHz BW = 20 MHz Type = Butterworth Orde = 5 I have made the design and i have attached it here. 56056 I want to ask the effect of transmission line connecting each lumped elements. Does it effect the frequency response of my bandpass f

## loking for code for analysis of transmission line using matlab

hello! has anybody have a simulation of transmission line in both temporel and frequency domain ?? best regards

## what is the meaning of 10dB input match?

in transmission line analysis, usually the mismatch will cause reflection and a reflection coefficient can be calculated. what is the meaning of 10dB input match?

## Coplanar Strip lines length

Do I understand right that your geometry is meant as a differential CPS without any embedding ground? That's rather unusual, because the E-field has effectively no bounds, so you get an open, leaky transmission line structure. I get a differential impedance of about 122 ohm with a different tool, however.

## Signal Integrity Procedure

Hello antarveena, I suggest you go through Hyperlynx Demos and Tutorials to understand the SI related simulations required. SI (Signal Inegrity analysis) 1) Cross talk 2) transmission line terminations 3) Stack up calculations etc... PI (Power Integrity analysis) This can also cause issues in your board. (...)

## Free software for microstrip dispersion problem

Hi everybody, Has anyone used free software (freefem, pdnmesh, meep etc.) for the full-wave solution to dispersive propagation constant and frequency-related (not static) characteristic impedance of microstrip (or any other inhomogeneous transmission line)? I know other software which does static analysis (ATLC, MMTL), but i need dispersive (...)

## .s2p in Agilent ADS for Skew Analysis of Striplines or ...

I can do one of two things, I think. I did some simulations of transmission lines of different lengths in Sonnet. I then exported the .s2p files in Touchstone format. Can I import those .s2p files into Agilent ADS and run some unit step or something to see the skew? If yes then how do I set that up? I'm new with ADS. Frequency range is 1-10

## Help!! about a "2-way power combiner/divider"!

I have got a "power combiner", it's power rating is about 1000W. Someone thought that it is "a quarter wavelength long tube shaped transmission line".But I Still:cry: can't understand how it works, Can anyone do some analysis for it? The attanchment is the photo of the combiner.
