Now I try to simulate by CST but I did not know how to use CST facing the transmission line with open or short. If there is somebody who can help me, thanks a lot.

Hi Victorfan2010,
You can design a transmission line on any substrate. Make the bottom plane as ground plane.
For an open circuit you can just leave the line open and for a short circuit the line should be grounded using a Via hole to ground.
A little caution for the length of line that it must not be \lambda /4 becasue the open/short characteristics are reversed in case of \lambda/4 line.
