Hello,

I am using the coupled microstrip model MCN4A. With the following values.

W1=100mil
W2=17mil
S1=20mil
L=500mil
H=60mil
Metal Thickness= 2.84mil

I get this "Local Warning"

MLI Model:For best accuracy, metal thickness should be less than line width.  Current values: T=0.072136mm, W=0.02159.

My metal thickness=2.84mil and my line widths are 100mil and 17mil.

Why am I getting this warning?  Can I believe my simulation results?
