Microstrip to CPW with Ground trace transistion in PCB.

Hi ,

I ve got a microstrip coming from a diode in the top layer of a 2 layer PCB & i need to change it to CPW with ground configuration to the bottom layer.
How to do this properly?
Thanks for any help,
Regards

I have no experience on this, but I think you can use HFSS to simulate. using vias.

you can use Agilent ADS line calc

To design the transition from microstrip to CPW?

My mistake, I coukd not visualize problem, Momentum should do the job. Can you share picture detaling the transition?

Hi,
I haven't tried.

Take a look @ paper below.
