cpw port dimensions in CST MWS

please help me by providing cpw feed port dimesnions in cst to exite the microstrip antenna

the cpw port dimension may vary depending on the antenna type you using. what time of antenna you using?
what i mean by antenna type is dipole, monopole, PIFA and etc..

sir its monopole antenna

here is the coplanar waveguide impedance calculator. you can calculate dimenstion of your coplanar waveguide using below link.

it cannot be monopole antenna. is there any groud plane underneath the antenna?

hi sir m, there is no ground plane on the other side of substrate, sir i calculated the slit width and feed width i.e S and W values, my doubt is what are the waveguide port dimensions to excite cpw.
