the impedance of the original stripline line is no longer maintained because of the additional thickness of that humungously-thick sheet of teflon being used between the two very-thick copper plates, which thickness looks like it has been vastly increased from the original dimensions.
I'm not sure if this is in reference to my picture or not, but if so the camera may be playing tricks on you. The teflon I'm using is .4mm thick (in fact it's not even teflon in that mock up, it's a sheet of paper). The copper is only 1.2mm thick (except the bent support bracket, it is slightly over 2mm). Both fall within what was specified in the design I used (which, to be fair, I have no knowledge of its effectiveness... but hey I wanted to try, this is how we learn).
Anyways I didn't mean to hijack the thread. Your notes about the dimensions of the cover are appreciated. I plan on making the enclosure soon!
Happy new year to all!
