Hi Chinmayi 

I tried the port size as recommended in the HFSS port excitation document. It did not correlate with a published work and another software. 

I used 5 to 10 times the height of the substrate 100um and the port was too narrow for very thin line widths.

Could you recommend the port size for a 6um width and 4um spacing coplanar lines on 100um substrate?
