Unfortunately it does not support transmission line I'm looking for.mr_ghz said:Try the free AppCAD tool from Agilents' website. You can calculate microstrip and striplines.
I'm already using LineGauge, but unfortunately transmission line I'm looking for is not supported in LineGauge. Are you suggesting that Microstrip formulas can be used to calculate Zc for vertically spaced microstrip transmission line? This web page (**broken link removed**) suggests that solution for my case is much simpler than microstrip case, but I'm not sure it's correct though...jian said:Please also try our free LineGauge Basic software from www.zeland.com. You can do the microstrip, stripline, coaxial line, rectangular waveguide etc. For parallel line, if you define the Substrate_Thickness_of_microstrip = 0.5 * Parallel_Strip_Separation, you will get Zc_of_Parallel_Strip = 2 * Zc_of_microstrip.
Thanks. Are these papers available on the web somewhere? I don't have IEEE subscription.sinatra said:Hello Pow.
The approximate formulas to find characteristic impedance and effective epsylon can be found in:
"Transmission Line Design Handbook", Wadel, page 249
Those equations were published in the following paper (according to Wadels book):
"Computer-aided design models for broad-side coupled striplines and milimeter wave suspended substrate microstrip lines", Bhartia, Bracash and Pramanick, IEEE transaction on microwave theory and techniques, vol MTT-36, 11 november 1988,p.1476-1481
and correction on
MTT-37 , 10 october 1989, p.1658
If I'm not wrong that is the right paper to get those equations. I probably have already read it and implemented some of the equations in one of my personal codes....
Hope it helps.

No. As jian already pointed out, my transmission line is:tapa said:If you need a calc for diferential lines, it helps you with u-strip and striplines.
