This one look interesting so here some info about it.

Most of the info came from these sites :

More pics can be found in the upper sites.

Drawings from elk again d-link 1800.rar but on You can find another two files which may be the same – I’m not shure.

Dimension between pcb plate and reflector is 9mm.

I’m not sure but, this antenna will be hard to reproduce because we do not have info about thickness of substrate nor dielectric constant of the material. So this is not a option to build and test for me right now.
