How can I make use of Dolph-chebyshev to linear microstrip?

Hi,

I'm designing 6 element linear microstrip antenna.

For the better SLL, I found dolph-chevyshev series.
However, I don't understand..
In the example(I found), there is only element spacing.
However, I want to design antenna operating some frequency.
Books or papers that I found are not exist such as frequency, both
width and length of antenna...

I really want to know how apply dolph-chevyshev to linear microstrip antenna.
please help me out on this matter!
