On straightening the traces, I wonder if rotating the parts (and 45 degrees is legal) would help.? Don't think that power leads are as critical.? IIRC, the bends might cause impedance changes and therefore reflections, but someone who actually does this might want to comment.
From what I remember about waveguides (seeing them), the minimum bend radius is frequency related, too.

The diodes are there because that's what HP did. I would also like to know the exact reason they did that too. :) It seems to work, so I'm sure there's a good reason for that layout.
The Coplanar waveguide specs are as follows:
PCB thickness = 1.6mm
Conductor width = 1.5mm
Conductor gap = 0.28mm
So that makes the trace Impedance = 50.1 ohms according to the Saturn PCB Design Toolkit.
Is there a benefit to going to a thinner board for signal integrity etc? I designed around 1.6mm thickness as it's the most common size (so cheapest, easiest, and quickest to get from China).
I'll have a go at straightening those traces too.
