KA-band Waveguide to Microstrip transition using a stepped ridge

Hi,

Can anyone share a KA-band Waveguide to Microstrip transition using a stepped ridge? I just need the x-y dimensions of the stepped ridge.

I can help for a E-band transition. Thanks,

I would grab one of these and have a look see. They are split block and come apart with screws:

There is an agilent application note somewhere on how the design was done, but I could not find the app note.

This is the transition with microstrip, it should be much easier than ridge.
This is my utility patent, and IPR belonged to my pre-employers, but the company discarded it now because the company is bankrupt.
So I gues you can use it freely now.



Here is the picture for 38G
