Hi all, I hope you can help me!
I’m simulating power combiners and dividers at HFSS but I don’t know how to make the characterization of the component.
There is only one parameter I can understand, the S11 (reflexion) on the output port of the combiner or input port for division.
The transmission parameters (S12, S13, S14…S1N) and the others reflections (S22, S33, S44…SNN) I get estrange values… High reflections values and low transmission values. The built component works well and the analysis with the network analyzer is the same of the simulated.

Could someone explain it me.

Thanks for advance!

I think you should obtain some basic knowledge of power combiner/divider from the "microwave engineering" by D. Pozar.
 

Man, I already read pozar, colin, Balanis, Harrington... They don't explain this. The behavior of one input of a combiner feed alone is different than all them feed together.
