[MLB-WIRELESS] Antenna design idea, probably not new.

[Jason Hecker]

All sorts of antennas can be made on a PCB.  A PCB yagi will have similar 
width and length dimensions as regular yagi so it'll be a it unwieldy 
without some sort of support like some strips of wood or metal.  You can 
get very fancy and make patch arrays (I've thought this would be a great 
option) and those funky omni spiral patches.  The problem with PCBs is the 
etching, but a hand drawn design dipped into the appropriate etching 
solution would be a cinch.  Or, you could use wood etching tools and 
scrape/gouge the unwanted copper off.  I have found in the past that 
permanent black ink marker pen leaves a good enough coat on copper to 
prevent it being etched as I used them to touch up boards I had made before 
UV exposure or etching.  Perhaps someone could do a stencil in PDF for that 
would be easy to whack onto a PCB...?

Food for thought.
