I had draw the amos-5 antenna by CST microwave studio following the paper . but when i simulate it doesnt work and show the error "The discrete port1 is inside perfect conducting material " How can i fix this problem? , THANK YOU

ps. it is still mismatch.

make a coaxial line for antenna and then feed it with wave port see patch example of CST
 

so i made a coaxial line and feeding . now i have gotten a problem again. The error show " Port 1 is inhomogeneously filled within the first3 mesh cells." i tried to fix it but it isnt still work.

i am really new for designing. many thank
Ps. i dont use balun for this time . i just want to simulate it before

you need to refine the mesh in the port because it needs more then 3 mesh cells in the same profile or you can extrude the coax to get at list 4 mesh cells.
