Hi friends,
As attached photo,I want to set wave port size of signal output.For this type is the coplanar mixed with stripline,how set the wave port size,W=?H=?(the trace parameter width=150um,H=204um).
Thanks in advanced,

I think it's not very difficult,so you can use parametric sweep to get the best size of your feeding.

What? Let's try to think, instead of trial and error.

The port area needs to cover the signal conductor and the corresponding ground returns.
 

...any stripline has the waveport extending from top gnd to bottom gnd and extend left and right ~7*width of trace (rule of thumb, not law of land...)

have fun
 
hi
how many ground u have ? why u want to use wave port try lump element?

I want to calculate the port impedence and the IL of path

What confuse me is the left and right sides have ground plane?whehter have different setting ?
 

hi
i confused .how was your structure ground ? are u have CPW structure?
 
It is multi-layer PCB for mobile.And microstrip is designed in internal layer.
