Wellcome

How...?? a curved wire is made....

Admin, got a question to you: recently I installed cst2019 and met a problem, it can not calculate 1/4 lambda transformator “wire above ground”.

AppCad gives preliminary results, but when I make a model in simulator it shows a weather.

[Admin 2545]

 I would like to see your results in the * cst file...!!

[vodkaman 1]

Sorry. wrong results

Admin, can you kill last 2 plots in previous post?

No, it doesn't. What do you mean?

[Admin 2545]

""" with the method shown above, you can delete the two ports...!!!

[vodkaman 1]

what for? I asked you to delete 2 PLOTS in THE PREVIOUS to Previous POST!

And the question was not about deliting ports.

So, what you’ve got? I have the same - nonsense! 

[Admin 2545]

[vodkaman 1]

Were are these in AppCAD?

Sorry my friend, but this has nothing to do with my question. 

My case is TRANSFORMER(transfotmator). 1/4 lambda TRANSFORMER. Zt=sqr(Za*Zf)

Admin, do you have a version? How to calculate quarter wave transformer in CST? 

[Admin 2545]

,,, my friend, explain to me, what you want to do with this quarter wave transformer in CST...???!!!

[vodkaman 1]

I need to conform antenna impedance (39 Ohm) and feeder (cable) impedance (50 Ohm). I need to do it with wire above ground. 

[Admin 2545]

[vodkaman 1]

Needed frequency is 2,6 GHz.

[Admin 2545]

Then do something like that....

Can you show the results?
