Sometimes I really have to wonder who is at the helm of the USPTO. Claim 1 is an overly broad description of an antenna assembly that has been with us for many decades. The other claims may also be overly broad, but my jaw dropped on #1 so that's the focus here.
I'll be digging for reference material, but I figured I would put this out here to organize the findings of others.
Does anyone have a textbook showing a crossed dipole antenna using coax as the phasing mechanism whereupon the crossed dipoles are arranged over a ground plane?
I note the word "microwave" is in claim 1, but that merely suggests the frequencies are high and wavelengths short and is only a matter of scaling Prior Art to the new frequency... Obvious to any practitioner of the art.
