i didn't get it...so what should I do...

The driven model can be used and you can see the S parameters

I have made the modifications as u said,the results are still not agreeing,

i am using hfss,please tell me how can i excite one port and obtain the output power at the remaining ports(if hfss by default assumes one port as input port or not),also tell me how to assign the phase difference between various ports

S12 means the transmitted power from port 1 to port 2
