Hi,
I want to model a simple Microstrip line(MS) in CST using discrete port. I had used the Waveguide port it has given me some results i want to compare with the discrete port.
Problem is that When i use a discete port between Ground and Microstrip line it gives me an error "The Port is...
Hi,
I want model a simple transmission line using FEM and i want to write a code in MATLAB. so can any one tell me a good reference of modelling equations.
I have Coded 1D FDTD for a transmission line modelling using the book "Computational Electromagnetics" by David B. Davidson but For 1D FEM...
The answer to your second question is that the Slot in Microstrip patch antenna is used for impedence matching. You can refer to Antenna Design book by Balanis for complete details for matching using slot and gain enhancement methods.
This book is a helpul reference for Microstrip patch antenna...
I think for a strip line balun antenna CST is ,probably, the most appropriate tool. Its GUI for structure design is very powerful, you can add your own VBA code lines, also its Transient Simulator is very fast as compared to other softwares.
CST is based on time domain techniques. If you have a...
Hi greta_garbo
For a single file of S11 or S22 etc you can just Right click on the file and then select copy.
Afterwards you can open a notepad file and paste in it.
It works for the S parameters v/s Frequency case.
Hi Victorfan2010,
You can design a transmission line on any substrate. Make the bottom plane as ground plane.
For an open circuit you can just leave the line open and for a short circuit the line should be grounded using a Via hole to ground.
A little caution for the length of line that it...
first learn the basics about splitter/combiner using Microwave engineering 3e by Pozar then u can use this paper.

try a resonant circuit. u will have a capacitor of known value then measure the resonant frequency
from this formula u can find the inductor value.
fr=1/2*pi*(L*C)^0.5.

conversion loss
Hi,
can anyone tell me what is the difference of conversion loss manupulation of active and passive mixer.
Pasive mixer conversion loss is directly used as insertion loss (or Noise Figure)
But active mixer gives you gain but its conversion loss is also mentioned (which...
The resistor helps in isolation of the ports. but the BAD return loss of the Difference ports(s22,s33) is due to impedance mismatch at those ports. you should try to tune the length of the lambda/4 section to get an optimum response.
