Dear all
I'm try to simulate a branch line couple in frequency band between 10.5-11.3 GHZ on substrate Rogers (h=0.508mm). the problem I have is that after optimization I can not get the -3dB amplitude in both port 3 and 2. the results are indicated in attachment. can anyone help me to find the solution? any support from you will be appreciated.
by the way I used the lumped port to excite the ports.
