## Transmission Line Calculator

Hi guys, I made a MATLAB tool which can be used for characterizing printed transmission lines at microwave frequencies. The input of the tool looks as follows: 113936 And it will give an output like this: 113937 It will give you the complex wavenumber, the characteristic impedance, effe

## Microstripe transmission line calucation

## Help need for designing of microstripline

I just tripped over a free AWR transmission line calculator available on their site for downloading. It also has a smart phone application, also free. Polar9000 is a great(but not free) tool. If you want more details Wadell's transmission line Design Handbook is a good reference. Azulykit You (...)

Hello- I'm using a few different microstrip calculators, but when I draw my trace, the suggested width (2.9mm) seems huge. calculator here: transmission line needs to be 50 ohms as it co

## Very small notch (and feed width) for a inset-fed microstrip antenna, is it correct?

The calculator over at gives me 0.156 cm microstrip line width These 1.56mm are consistent with results from another transmission line calculator (AWR txline). This is a reasonable, expected value for 50ohm line impedance at 0.8mm substrate height. I have not (...)

Hi all, transmission line calculators in ADS and AWR are valid over what frequency range? and Can i have formula for finding length width and spacing for coupled microstrip line? thanks

## Substrate thickness for L-Band

If you use a transmission line calculator as TX line from AWR you will see that for the same dielectric, at high frequencies, using thicker substrate you get lower loss than using thinner substrate. AWR | TX-line | Optional Products - TX-line

Hi All, I'm new to ADS. I'm a student, and needed your help, I want to design a Microstrip transmission line using ADS. I know Zl = 150-75i ohm , , Zo= 75 ohm , l ( in terms of lambda) , Di-electric constant= 2.22, h= 3 mils, Zg=50 ohm Need to find Zin,Reflection Co-efficient, S11 ( at input).If you can guide me how to go about it, i will rea

## Grounded Differential Coplanar Waveguide calculator

Most of the dedicated TL tools doesn't have this option, only if you use a full EM simulator. You can make your own spread sheet using formulas provided by Wedell's book "transmission line Design Handbook" page 196, 197, 198 (attached)

## transmission line design

Hi .. Is there any simulator or formulas available for designing a 50 ohm transmission line for patch antenna. can i get some theoratical formulas for designing a inset fed patch antenna??? Thanks in advance

## microstrip patch antenna design

You have to know what is the Dielectric of the material you are using to get λ εr = ?. If you put those dimensions listed on a PCB w/ εr = 4.3 it might be good, but if your PCB has an εr = 9 it might be way off. Look for APPCAD or go to Rogers PCB website and look for a free web transmission line calculator. (...)

## 50 ohms transmission line and calculating inductance

I have a microstrip line (rf trace with Zo=50 ohm). Somewhere on the trace I need to create .67nH inductor. What formula do i use to do this? or/and What free sw is available that I can use to do this? I found a calculator that finds the inductance if you provide the: w =width of the strip in inches, b = the length in inches, h = the d

## Coplanar Waveguide Design

## Trace width calculator

There are free PCB transmission line 2D field solvers that can be used. TNT ( ), has a good interface and gives good results. MDTL ( ) isn't as well developed, but it still gives good results for differential traces. If all you want are close numbers, and precision isn't requ

## Incident wave and its power?

One way to determine the power in HFSS is to use the field calculator and integrate the Poynting vector over the face through which the incident wave passes. This will give you Power flow. You can then adjust your HFSS / Fields / Edit Sources for the Incident Plane Wave to deliver the expected power near your transmission line. Make sure (...)

## Calculator for plotting smith charts

Hi friends, I found this nice calculator for RF Design. It's very useful to plot smith chart without using actual smith chart paper so that there is no drawing and calculation error. It can be used for students who start to learn transmission line and impedance matching network like beginner course. It serves as a reference for expert (...)

## Easy software for transmision lines simulation

Hi all! I am looking for some small program wich allows me to simulate simple transmission (I do not even need to modelate them as real tx lines, i.e. microstrip, guideline, etc) lines. I just want to see how the line behaves when a square pulse is sent and, for example, a resistor terminator is placed (...)

## Simulation of a microstrip transmission line

Hi Cheng ! It's impossible to represent a microstrip T.L. with just impedance and phase becasue this T.L. is distributed and has phase accumulation as a function of a distant (length). Its catagorized as distributed T.L. and not as lumped (discrete). I can know for sure that you can simulate and calculate any discrete/lumped
