5-way Bagley Polygon power divider simulation

I have come across a 5-way Bagley Polygon power divider. But i am unable to simulate it to get the desired results. can anyone help?

relative permitivity = 2.45
impedence should be at 50ohm
and 44.7ohm for the ring
the frequency is at 5Ghz

so im setting the width to be 2.8(50ohm) and 3.2(44.7ohm)

detail of the power divider is shown here below:
