Thank u all for turning back.
AKHİLPAULV, I am attaching the screenshots here for you. One is showing the error, one is showing according to what I put the waveguide port.
RADIOHEAD, I did what you said. It seems fine.I wasn't adjusting 50ohm btw, I know that when u put a port in cst, it is coming by 50ohm default(that is why I said 50 is adjusted). When I change the both impedances by using "renormalizing port impedances" option under post processing, difference occurs
I just put the ports, simulated and then I wrote values for both of them 50 and 100ohm as you said, so is that the way of implementing impedance matching on cst? If so, thank you a lot.
BRYSON, the transmission line is a tapered line, broad side is 6mm wide, while the narrow side is 2mm wide. The thichness of the transmission line is 0.5mm. How much narrow did you mean?
