    how simulate a branch line couple in HFSS correctly

    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...

    how to insert Via in ADS layout???

    hi all I am simulating a microstrip design in ADS 2011 layout. I don't know how to insert via properly :-( actually I defined via hole while defining substrate and there is a component named via in library but when I add it to my design no thing extra appears in 3D view. can anyone tell me...
