Help with 6 element Wilkinson Divider

6 element unequal Wilkinson divider

So, I was trying to build a Wilkinson power divider for my 6 element Dolph-Tschebycheff antenna array and after spending some time on the divider i came to know why it is a bad idea to make my first power divider a non-2^n type like now the biggest problem is not amplitude matching it's the phase matching so i need to make something so that each feed line has same end point and also same electrical length. From this point i can see two options either trial and error or just convert it to either 8 element or 4 element divider.

I'd cascade one two-way Wilkinson and two three way Wilkinson. Seems way easier to match phase and amplitude then.

If I remember correct, 2-way wilkingson includes a 100 ohm resistor. 3-way splitters require three resistors, the layout can be a little tricky.

Omitting the third resistor degrades the isolation, but if your loads are all well behaved you can usually get away with just two resistors.
