impedance coplanar stripline
Hi,
I am simulating a Coplanar Strip Line on ground plane. I m using waveport at one end with 2 modes....and differntial port with reference impedance of 100Ω in differential mode and 25Ω as common mode reference. The waveport is normalized to 50Ω impedance. I am connecting a lumped element say a resistance of 100 Ω at other end of the coplanar strip line. I am defining it by a rectangle of lumped RLC boundary.
I am trying to calculate the ZL in my case (should be ≈100Ω), by using standard transmission line equations. I am considering the complex γ, for my calculations but ..... I do not get the correct approximation.....for load impedance. I am not able to validate my results....can soem one look into my problem and comment on it...
any help is appreciated.....
