Results, Admin, results!!! Were are they?
-
What do you mean? You think I’m lying?
-
I did, unfortunately.
-
Can you show the results?
-
Needed frequency is 2,6 GHz.
-
I need to conform antenna impedance (39 Ohm) and feeder (cable) impedance (50 Ohm). I need to do it with wire above ground.
-
Admin, do you have a version? How to calculate quarter wave transformer in CST?
-
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) http://www.antenna-theory.com/tutorial/txline/transmission5.php

Remember this? https://www.lan23.ru/forum/node/10547?p=174362#post174362
-
Were are these in AppCAD?
-
So, what you’ve got? I have the same - nonsense!
-
this one
-
what for? I asked you to delete 2 PLOTS in THE PREVIOUS to Previous POST! And the question was not about deliting ports.
-
No, it doesn't. What do you mean?
-
Admin, can you kill last 2 plots in previous post? T2.6.cst
-
Sorry. wrong results
-
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, can you make polygon sample for me, so i can sweep it to wire?
-
I saw history list, and there are too many elements for this simple structure. The idea is to simplify model up to 2 sweepcurves.
-
Yes, that’s what i said in other words Admin, can you help me to set parametric polygons for this antenna? Here is diagram, correct me, if you please.
-
I wanted to check how broadband it is. And 50 Ohm can be obtained by narrowing the gap at feed point (in some limits).
-
Sorry, I don't know how to control size of the pictures.
-
Here is what I've got for 50 Ohm:
-
Oh, shit! How should i know this?
-
To which value should i change “k” parameter?
