meander antenna in ADS

I am designing meander antenna in ADS for f0=95MHZ. I would like to know how to define the coplanar waveguide (CPW) port for structure. Also for solver setup if i m simulating my structure from 50 to 200 MHz range then what should be the appropriate mesh frequency and number of segments per wavelength. Also the value of Nmax in frequency definition.

thanks!
