port 1 is inhomogenously filled

[Divya.S]

I am new to CST and facing lot of difficulties. I am trying to bend the cpw fed monopole antenna but whenever I am simulating I am getting the error "port 1 is inhomogeneously filled within the first three mesh cells. Cannot start solver."

I am also enclosing the structure that I have simulated. Help urgently needed.

I have also attatched the file in the zipped format.Plz chk it

I have looked at your file and the problem is the location of your port. I have amended the port dimensions and locations and this has fixed the port problem. The S11 however shows a poor match so look at your material and see what the problem is. You could perhaps use an FR-4 substrate and copper at the top? Just a suggestion! I have attached the amended port dimensions. Hope this helps!
