Power divider: reverse engineering strategy

[yefj]

Hello , I need to recreate the following dividing network .
I only have photo.
the branches are angled and the transformers are triangles ,why is that?.
could you share some impedance logic that could fit the structure below?
Is there some theory regarding this structure?
Thanks.

Where does the photo come from, what is the equipment?

That looks like sixteen devices are to be operated in parallel. The input is divided into sixteen parallel paths, then recombined to form the output.

The length of the tapered (triangular) transformers will almost certainly be λ/4, at the velocity factor of the PCB. The width of the taper, at its ends, will set the input and output impedance.

The two lines involved in each divider or combiner, separate at 90°, in order to avoid magnetic coupling between the two branches.
