4:1 unequal wilkinson power divider

I hav to design a 4:1 wilkinson unequal power divider. I am following the IEEE paper on tht n pozar. I hav calculated the impendences for the unequal power divider. My frequency of operation is 1.5Ghz, dielectric value is 1.5, h=1.57 ie he height of the substrate . Can u tel me how to calculate the width of the conductor as well as the length of the conductor n how to proceed after tht...n plzz tel me whether my approach is correct or not.......plzz help
