Thanks to shlomo22 for the compressed file! Who has the other one?
 

exitar una cpw hfss

Hi guys , In the tutorials it is written that the wave port size should not exceed lambda/2 in any dimension but also its width should not be less than 3(2g+w).

In my case I have lambda=25mm
g=0.23mm
w=8mm , all these for Zo=50 ohms.

Now my waveport width comes out to be 25.38mm,
but lambda/2=12.5mm.


So what shoould i do now!!!!!!! Any ideas!!!!!!
 

coplanar waveguide lambda/20

really want this file, need help!!
 
Thanks for the explanation, it really helps!
 
the file port_tutorial_CPW.zip is really excellent ...
