microstrip line transfer to CPW structure

Hi, everybody

Who can tell me if conventional microstrip line structure transfer to CPW structure?

Thanks in advance.

I think transfering from Microstrip to CPW will be quite straight-forward. You may just need have the following layout

Top View
--------------------------
microstrip ground |
|\\o\\\\\\\\\\\\\\\\\\ CPW ground
|---------------------
|
----------------------------------------
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ CPW Ctr Conductor
----------------------------------------
|
|---------------------
|\\o\\\\\\\\\\\\\\\\\\ CPW ground
microstrip ground |
--------------------------

You need to have some vias to connect the CPW ground to the microstrip ground underneath. Also, you may need to optimize the dimensions for good matching.

Regards.
