inside
bigger than patchs and close to 4mm or so the screws touch it on the current centers of the patch

ABS should be like 2.8 of dielectric constant and 1.5 mm width ...try to keep 5mm to aluminum reflector inside , but it's tricky...not a lot of space
some wifi cards don't like it so it must be high VSWR...channels from 1 to 11 all show up...poor signal though...

OK , "dude" ...already built it on a notebook ABS cover...with aluminum foil...CST simulation would be great to fine tunning it...
PD: I'm NOT getting 16dbi and a lot of VSWR

3dbi more with Directors aparently...

Hi , guys it would be nice if some generous soul simulate this one...
The original is 6 elements over 0.787 ptfe , 2.1 dielectric constant...
