Can anyone identify this tiny 2.4/5.8GHz antenna connector?
It's quite hard to tell but here is some hints on possibilities:


MMCX connector: used for wifi antenna in notebooks http://en.wikipedia.org/wiki/MMCX_connector
U.FL connector: also used for wifi antenna in notebooks, but more recent

MC-Card connector ( http://www.deltarf.com/pdf/DeltaMCcard.pdf )


The connector you have seems to be to long for the small U.FL, also the U.FL central pin seems to big to fit your connector.

I'll said that's a MMCX connector but not sure at 100%.
