Can anyone guide me how to plot Odd and Even mode impedances of a 4-port microstrip directional coupler. Driven Terminal Modal
Quick question - which tool are you using for your analysis?
Karthik I am using HFSS 15.0
Hi JarHead,I am not tried this method to compare but you can try this suggestion and verify it against known value, to see if it works:
Set solution type: Driven terminalDraw two terminal lines while creating waveport.Set differential ports (Right click on the excitation and set proper pair). Your 50Ohm ports will be then 100Ohm for diff, and 25 Ohm for common.Run sim, and then Zeven= 2*ZcommonZodd=Zdiff/2Thank you,
@JarHead have you tested the solution mentioned ?
