ask： define microstrip port in cst?

hi all
i newbie in CST software.,
i design a microstrip antenna with feed line in CST, but i still confuse about define a port in CST..
when i use a discrete port, it has an error..
can you help me..
thx..

can you tell what error does it give?

Dear yuda23
in cst when u model microstrip (anteena or filter )u should add wave guide port not descrit port descrit port for dipole antenna

look at the examples in CST. Patch antenna is there. look for the feeding arrangment. Its quite straight forward.
