Wilkinson power divider 4-1

[belma1511]

Hello,

I'm simulating a 4-1 Wilkinson power divider (operating frequency f=5.5 GHz and characteristic impedance Z=50Ω) in Ansoft Designer and when I included bends in the circuit,the S-parameters shifted to much from the central frequency. Can anyone have a look at it and suggest how to fix the problem?

When u add bends,u are adding extra electrical lengths,
So you need to tune/reduce total length to get back the
Required response.

I thought Ansoft Designer don't take into account the electrical length of bends unlike HFSS?
