I am trying to simulate a coupled coplanar waveguide in uSimmics 5.8, but there are no models for this type of line. Has anyone else encountered this situation or found a solution for simulating this type of line?
There is a very helpful calculator and equations for conductor-backed edge coupled coplanar waveguide given by Takayuki Hosoda at http://www.finetune.co.jp/~lyuka/technote/cbcpw/edge-coupled-cbcpw.html . I have made a subcircuit for the coupled line shown in the attached screenshots.
